|Procedures for Working with MPTP |
|(1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine) and |
|MPTP Treated Animals |
| |
| |
| |
|INTRODUCTION |
| |
|MPTP (1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine) is a neurotoxin used to induce Parkinsonism symptoms in experimental models of Parkinson’s|
|Disease (PD). MPTP can produce irreversible neurological damage indistinguishable from PD in humans and animals. The inappropriate handling of |
|MPTP may result in exposure and irreversible neurological damage to research staff. |
| |
|MPTP is lipophilic which freely and rapidly crosses the blood-brain barrier. It is metabolized to MPDP+ which is oxidized to the active |
|metabolite MPP+. MPP+ is the active metabolite that results in neuron cell death. Excretion of unmetabolized MPTP occurs mainly during first day |
|post injection while MPTP metabolites are excreted up to four days post injection. Excretion is mainly in the urine; some has been found in the |
|bile. MPTP metabolites in urine are expected to be ionized and not volatile and be absorbed by the bedding. |
| |
|Exposure to staff may occur via needle sticks, aerosolized droplets, skin exposure, or inhalation of aerosols from MPTP-contaminated bedding. |
|Exposure potential is greatest during preparation, administration, and when handling the animal bedding during the first four days after |
|administration. |
| |
|The purpose of this Standard Operating Procedure (SOP) is to define the safe work practices and appropriate medical management for staff working |
|with MPTP in your research laboratory. A lab-specific SOP must be approved by EH&S prior to Institutional Animal Care and Use Committee (IACUC) |
|approval. For questions or assistance in completing the SOP that is specific for your laboratory, contact EH&S at 206-221-7770. |
| |
| |
| |
| |
|PRIOR TO BEGINNING WORK WITH MPTP (All of the following procedures are required for employees who plan to work with MPTP or enter MPTP work areas|
|up to four days post administration and after first cage change) |
| |
|Medical Management: |
| |
|Prior to initiating work with MPTP, the Principal Investigator (PI), , and his/her staff must contact the Employee Health Center (EHC) -UW |
|Campus (UWC) at 206-685-1026 to schedule an appointment for evaluation and to receive the post-exposure prophylaxis (PEP) of Selegiline |
|hydrochloride. The EHC-UWC will prescribe the Selegiline if indicated and there are no contraindications. The EHC MPTP handout is attached in |
|Appendix 1. |
| |
|Selegiline is obtained prior to beginning work with MPTP. Selegiline must be immediately available for use in room in case of exposure. It |
|must be kept in the white capped container labeled “FOR MPTP USE ONLY.” Each staff person working with MPTP must have a medical clearance and |
|prescription. The container must be regularly checked to ensure it is in its proper place and the use date has not expired. If expired, contact |
|the EHC-UWC (206-685-1026) for collection or instructions for proper disposal. |
| |
|The PI, , must send all personnel who intend to work with MPTP to the EHC-UWC prior to beginning work and annually thereafter for evaluation |
|and determination of their ability to successfully take Selegiline. |
| |
|Respiratory Protection: Respirators are required when working with MPTP-treated animals. You MUST be enrolled the University’s Respiratory |
|Protection Program prior to wearing a respirator. The PI must complete a Respirator Request to initiate the process of respirator medical |
|clearance, training and fit testing: . |
| |
|Laboratory Set-up: |
| |
|Order PRE-WEIGHED injectable form MPTP from the manufacturer. MPTP must be purchased in hydrochloride or tartrate salt form rather than as a |
|free base. The chemical must be stored in a secondary container in a lock-box in or adjacent to the fume hood. Only people who work with MPTP |
|will have the key to the lock-box. Post Appendix 2 on the fume hood. |
| |
|MPTP must be entered into the chemical inventory (MyChem) system for all laboratories and rooms where the chemical will be stored. |
| |
|The protocol / procedures for new PIs and research staff who have not worked with MPTP in the past should be peer reviewed by another PI familiar|
|with handling highly toxic chemicals. |
| |
|It is very desirable to practice procedures using a surrogate before handling MPTP to ensure all necessary equipment is available. |
| |
|The PI or laboratory manager must identify, in writing, specific individuals authorized to handle MPTP and those who will be handling |
|MPTP-treated animals within four days post treatment. |
| |
|Check for proper operation of the eyewash and fume hood prior to handling MPTP. |
| |
|Establish procedures for make-up of 1% bleach disinfectant solution on a daily basis. |
| |
|Ensure receptacles and procedures for correct waste disposal (including hazardous waste and incineration waste) are in place prior to initiation |
|of work. |
| |
|Employee Training and Notification: |
| |
|The PI, , must ensure his/her staff are trained on this SOP, review the MPTP Material Safety Data Sheet / Safety Data Sheet (MSDS/SDS), the |
|hazards of MPTP, and the proper use of equipment (syringes, fume hood, emergency eyewash, etc.) and personal protective equipment (PPE) prior to |
|beginning work. This training must be documented in Appendix 4. For assistance, contact EH&S at 206-221-7770. |
| |
|The following EH&S training must be taken and documented prior to beginning work: |
|Online fume-hood training |
|Managing laboratory chemicals |
|Respirator training and fit testing |
| |
|EH&S Notification: Notify EH&S (206-221-7770) one week prior to beginning initial work for review of the final SOP and to check that training and|
|pre-work actions have been completed. After the initial EH&S SOP approval, mock-work using surrogate materials or the first experiment may be |
|observed by EH&S staff to evaluate work practices and procedures. Annual reviews may be conducted by EH&S staff. |
| |
|ACCIDENTS, INJURIES, AND POTENTIAL EXPOSURES (Post these procedures in the laboratory where the work will be conducted): |
| |
|In the event of a recognized percutaneous or mucous membrane exposure to MPTP: |
| |
|Immediately take prescribed Selegiline as directed by the EHC-UWC. |
| |
|Initiate first aid at the worksite: |
|Contaminated skin should be washed with copious amounts of soap and water for 15 minutes. |
|Contaminated eyes and mucous membranes should be irrigated for 15 minutes, using saline or water. |
| |
|Go directly to the University of Washington Medical Center Emergency Room (ER). Be sure to give your name, your exact location, and that you were|
|exposed to MPTP. |
| |
|Notify the PI, at as soon as possible. If he/she is not available, contact at . |
| |
|Report the incident on the UW Online Accident Reporting System (OARS): |
| |
|In the event of a suspect exposure to MPTP: |
| |
|Immediately initiate first aid at the worksite as outlined above. |
| |
|Go directly to the University of Washington Medical Center Emergency Room (ER). Be sure to disclose your name, your exact location, and that you |
|may have been exposed to MPTP. Based on the likelihood of exposure, Selegiline may be recommended. |
| |
|Notify the PI, at as soon as possible. If he/she is not available, contact at . |
| |
|Report the incident on the UW Online Accident Reporting System (OARS): |
| |
|Fume-hood alarm: |
| |
|In the event the safety monitor is in alarm, lower sash until it returns to normal, then press the reset button. If monitor continues to alarm |
|with the sash below 18”, cover caging, stop work, and call EH&S at 206-543-9510 to assess whether maintenance is needed. If fume-hood |
|maintenance is required, follow procedures outlined in section VIII, Emergency Transport of MPTP-Treated Animals. |
| |
|Spill procedures |
| |
|Spills inside a fume hood: |
| |
|Close the fume hood sash. |
| |
|Remove any contaminated PPE, wash hands for 15 minutes, and replace PPE. |

| |
|For further information, contact the EH&S EP at 206-543-0467 for advice as to whether a contractor should come in and clean up the spill. |
| |
|PERSONAL PROTECTIVE EQUIPMENT (PPE) |
| |
|PPE must be worn whenever working with MPTP or MPTP-treated animals and their waste within four days of last administration. These activities |
|include preparing MPTP solutions, administering MPTP to animals, entering MPTP-animal room within first four days of administration, first cage |
|change: |
|Standard vivarium scrubs |
|Rear-closing disposable water-proof gown |
|Disposable liquid resistant sleeve covers (wrist guards) |
|Double nitrile gloves |
|Chemical safety goggles or faceshield |
|N95 disposable respirator |
| |
|Cage changing: The cage changes must be done every seven days. When possible, cage changes should not be performed for the first four days |
|post-injection. However, protocol-specific dosing schedules may require cages to be changed within four days post-injection. With the current |
|dosing regimen, cages will be changed on days 1 (prior to the first MPTP injection), and days . Cage changes on days will involve |
|MPTP-contaminated bedding. |
| |
|Frequent glove changes are recommended. Change gloves immediately if their integrity has been compromised (e.g., punctured, torn) or if |
|contaminated. |
| |
|Protective clothing should be changed prior to entering non- MPTP designated areas. |
| |
|Remove PPE in the following order: |
| |
|Outer gloves (place in MPTP-waste to be incinerated). |
| |
|Put on a new pair of gloves. |
| |
|Remove goggles/face shield. Spray goggles with 1% bleach. Wipe. |
| |
|Sleeve covers (to non-contaminated regular trash). |
| |
|Disposable gown (to non-contaminated regular trash). |
| |
|N95 respirator (to non-contaminated regular trash). |
| |
|Outer pair of gloves (to non-contaminated regular trash). |
| |
|Exit the MPTP administration area, remove inner pair of gloves and wash hands. |
| |
|Dispose of protective clothing which is not contaminated into the regular trash. Dispose of contaminated clothing into hazardous solid waste |
|container for collection. When waste bags are full, remove from the waste cans, tie shut with a label indicating either “MPTP-contaminated waste |
|for incineration” (orange bags), or “Uncontaminated waste” (black bags), spray with 1% bleach and leave next to the door for disposal by |
|Comparative Medicine staff. See Section X (Waste) for more details. |

| |
| |
| |
|RESEARCH STAFF ONLY: MPTP PREPARATION AND ADMINISTRATION TO ANIMALS |
| |
|As with all highly hazardous chemicals, two research staff must be available at all times when working with MPTP, administering MPTP, and working|
|with MPTP-administered animals until four days post last administration. The second person does not have to be in the room during handling or |
|administration but must be readily available in the event of an emergency. |
| |
|During preparation and administration of MPTP: All of Room is restricted to only those research staff authorized to work with MPTP. |
| |
|The approved fume hood in Room for MPTP work is restricted to staff authorized to work with MPTP and MPTP treated animals for a minimum of |
|four days after last MPTP administration. PPE must be changed prior to exiting the room. The approved fume hood is the designated location for |
|preparing, administering, and housing animals. |
| |
|All animal procedures and housing must be performed in a centralized animal facility. For the first four days post-injection, the door to the |
|MPTP animal room and the approved fume hood must be posted with the appropriate MPTP signs so it is clear that the MPTP and treated animals are |
|present. Appendix 2 must be posted on the fume hood when animals administered MPTP are present. The red MPTP sign in Appendix 3 must be posted on|
|animal housing room door. |
| |
|Only trained animal husbandry and veterinary staff may enter the room up to four days after the final administration. |
| |
|MPTP and MPTP solutions must be stored in labeled, tightly capped containers. The container label must include the identity of the hazardous |
|contents (i.e., MPTP) and the appropriate hazard warning (i.e., neurotoxin). |
| |
|MPTP, as received from the manufacturer/vendor in its original undiluted form, must be stored in a lock box inside or adjacent to a clutter free |
|certified and approved chemical fume hood. Only people who work with MPTP will have the key to the lock-box. The box will be permanently attached|
|to the side of the fume hood / to the wall adjacent to the fume hood. If the lock box is outside the hood, the MPTP must be kept in a secondary |
|container inside the lock box and while moving it between the lock box and the fume hood. |
| |
|The fume hood must be posted with the red MPTP sign in Appendix 2. |
| |
|MPTP solutions must be prepared in a certified chemical fume hood. Appropriate PPE must be worn, as noted in Section III. All work surfaces must|
|be covered with absorbent, plastic-backed, disposable absorbent pads. Make the 1% bleach solution and prepare the fume hood with all necessary |
|materials (pads, paper towels, syringes, decapicones, syringe tray, etc.) prior to opening the lock box. |
| |
|When the lock box is adjacent to the fume hood, it is safer and more convenient if the back-up person opens the lock box, allowing the primary |
|investigator to transfer the MPTP from the lock box to the fume hood. |
| |
|Use only needle-locking syringes or disposable syringe-needle units (i.e., needle is integral to the syringe). Used disposable needles must not |
|be bent, sheared, broken, recapped, removed from disposable syringes, or otherwise manipulated before disposal. Never leave the tip exposed on |
|work surface. After each injection, immediately place the syringe-needle unit in a sharps disposal container located in the fume hood or |
|approved containment. |
| |
|Disposable labware should be used when preparing MPTP solutions. If non-disposable glassware is used, it must be triple rinsed in 1% bleach |
|solution prior to washing. The rinsate must be collected and disposed by EH&S as hazardous chemical waste (see section X: MPTP Waste). |
| |
|When all work with MPTP is complete, place th MPTP vial in the lock box/secondary container. Change outer gloves, then spray the exterior surface|
|with 1% bleach and wipe down. Carefully remove all absorbent pads and dispose as hazardous chemical waste. Wipe all surfaces with a 1% bleach |
|solution and double bag the wipes or paper towels and discard with regular garbage. TURN THE HOOD LIGHT OFF. |
| |
|Tie the MPTP-contaminated waste bag closed, spray down the exterior surface with 1% bleach, then place in a second bag labeled as hazardous |
|chemical waste. Tie the second bag closed and leave in the room for disposal. |
| |
|Change the non-contaminated waste bag. Tie the full non-contaminated waste bag closed and leave in the room for disposal. |
| |
|Remove PPEinto the non-contaminated waste located next to the door, and exit the room. |
| |
|If emergency maintenance must be done during the first four days after the injection, stop all work and decontaminate the area. Ensure that all |
|concentrated and dilute concentrations of MPTP are closed and properly stored. Please escort the worker into the space and remain in the room |
|during the entire maintenance. If work needs to be done in the fume hood, the animals should be moved to another fume hood following the |
|procedures outlined below. The sign should remain on the door and fume hood to inform other staff of the MPTP and MPTP-treated animals. After the|
|four days post injection, no extra PPE is required in this space and any requirements for escorts will be determined by the Department of |
|Comparative Medicine staff. |
| |
| |
|TRANSPORTING MPTP |
| |
|MPTP containers must be transported between rooms using the following method: |
| |
|MPTP solutions must always be transported in a labeled, sealed, primary container within a sealed, leakproof, unbreakable secondary container. |
| |
|The primary container must be placed inside a secondary container lined with a plastic-backed pad or other absorbent material. |
| |
|If a spill does occur outside the lab, follow the spill procedures above; cordon off the area and restrict access until all of the MPTP has been |
|cleaned up. |
| |
|The secondary container must be cleaned with 1% bleach solution after each use. |
| |
|All PPE must be removed prior to leaving the designated area. |
| |
|PPE must be put on prior to handling the MPTP container in the new space. |
| |
|All locations where MPTP will be stored must be entered in MyChem. |
| |
| |
|EMERGENCY TRANSPORT OF MPTP-TREATED ANIMALS |
| |
|In the event of an emergency requiring the treated animals be moved before the first cage change, contact EH&S (206-221-7770) and the Office of |
|Animal Welfare. |
| |
|A new fume hood and room for procedures and animal housing must be approved by the Office of Animal Welfare and EH&S. |
| |
|in a fume hood, prepare animals for transport: |
| |
|Secure the cage tops to the cage bottoms with tape. |
| |
|Wipe down the cages with 1% fresh bleach solution made daily. |
| |
|Pack up to four cages in the transport box. Transport boxes may be obtained from the Department of Comparative Medicine. |
| |
|Secure the transport lid using the snaps. |
| |
|Carefully transport the animals to the new fume hood or animal housing room. |
| |
|Ensure no cage has opened during transport. |
| |
|Remove cages from the transport box into the chemical fume hood. |
| |
|ANIMAL HOUSING |
|Research staff will be responsible for changing the animal cages during the course of the experiments and for the final cage change four days |
|after the last injection. The Department of Comparative Medicine staff will ONLY care for the animals if there is a sick animal, flooded cage, |
|or other special circumstances. |
| |
|Animals will be housed in room , where the fume hood is located in a centralized animal facility. |
| |
|The animals will be housed in disposable cages; all bedding will remain in the cages and be disposed of at the same time/re-useable cages. |
| |
|For the first four days post-injection, the fume hood in room is the designated location for preparing, administering, and housing animals.|
|The door to each MPTP-animal room must be posted in such a manner that it is clear that the fume hood contains MPTP-treated animals. The fume |
|hood may only be used for the MPTP work (preparing, administering MPTP and housing animals). Post the sign in Appendix 2 on the chemical fume |
|hood . |
| |
|The animal cages must also be properly labeled with cage cards stating “MPTP –neurotoxin.” |
| |
|For the first four days post-injection, cover the cages with filter bonnets. Place the cages in a certified chemical fume hood. Ensure the lids |
|are secured to the cage. |
| |
|No animal husbandry staff is allowed in the animal housing room during the animal procedures. |
| |
|When possible, cage changes should not be performed for the first four days post-injection. However, protocol-specific dosing schedules may |
|require cages to be changed within four days post-injection. |
| |
|Four days after the final MPTP injection, the animals may be transferred to clean, standard caging and the MPTP door signs and cage tags may be |
|removed. |
| |
|Cage change should be performed wearing appropriate PPE (section V) and in a chemical fume hood. Work atop absorbent pads. The fume hood should |
|be wiped down with 1% bleach solution and water after use. |
| |
|Dirty reusable cages and reusable racks should be wiped down with 1% bleach solution for 10 minutes, rinsed with water, and covered with a full |
|drape. |
| |
|Dispose of bedding by misting the bedding with minimum 1% bleach solution, carefully place bedding into plastic bag, then into incineration |
|container. Alternatively, bedding may be completely saturated with 1% bleach solution, allowed to sit for 10 minutes, and then double bagged and|
|disposed with regular trash. |
| |
|Reusable caging, cage racks and reusable water bottles can be sprayed with 1% bleach solution, allowed to sit for 10 minutes, wiped down with |
|paper towels and then bagged for transport to facility cage wash. Any extra water in the water bottle should have 1% bleach added and allowed to |
|sit for 10 minutes. |
| |
|The use of special PPE is not required after the animals have been transferred to clean cages (after four days post-injection). |
| |
|MPTP WASTE |
| |
|Unused concentrated MPTP (including empty vials) waste is managed as hazardous chemical waste through EH&S. See |
| |
| |
|Spill cleanup materials, soiled PPE, and absorbent pads contaminated with MPTP should be double bagged and managed as hazardous chemical waste |
|through EH&S as above. |
| |
|Grossly contaminated solids can be decontaminated with 0.1 N hydrochloric acid or 1% bleach. After decontamination, the solids can be disposed |
|with regular garbage or reused. The liquid waste containing dilute MPTP and decontaminant should be managed as hazardous chemical waste through |
|EH&S. |
| |
|All other solid waste, including gowns and gloves, believed not to have contact with MPTP can be double bagged and discarded with regular |
|garbage. |
| |
|Animal bedding: Bedding from first change (four days after last administration) must be incinerated. Complete the UW Biomedical Waste Account |
|Request Form to arrange for proper containers and pick-up. Specify that pick-up is for incineration. Bedding from subsequent cage changes can be|
|double bagged and discarded with regular garbage. |
| |
|Animal carcasses: Carcasses that have received MPTP within the last four days must be incinerated. Complete the UW Recycling and Solid Waste |
|Biomedical Waste Account Request Form to arrange for proper containers to be delivered and pick-up. Specify that pick-up is for incineration. |
|Carcasses that have not received MPTP in the past four days can be double bagged and discarded with regular garbage. |
| |
|Sharps are collected in an appropriate sharps container, and picked up by the UW biomedical waste contractor for incineration. |

| |
|Background: MPTP (1-methyl-4-phenyl-1,2,5,6 tetrahydropyridine) and its analogues (ie., 2’-CH2-MPTP or 2’-NH2-MPTP) are neurotoxins used in |
|animal models to simulate Parkinson’s syndrome. Low dose exposure (ie. 0.1mg/kg body weight) may cause irreversible neurological damage to |
|dopamine neurons (exposure may result in Parkinson’s disease-like syndrome). |
| |
|Definition of Exposure: |
|Skin puncture with materials contaminated with MPTP or analogues |
|Ingestion of MPTP or analogues |
|Mucous membrane exposure (ie nose, eyes, mouth) |
|Inhalation of MPTP or analogues powder |
|Cutaneous exposure if skin is broken (i.e. wound) |
| |
|Immediate Post-Exposure actions: |
|Follow EH&S OHS |
|Post exposure prophylaxis: initiate immediately following exposure |
| |
|Treatment for significant exposures to MPTP is four (4) selegiline (Eldepryl) 5 mg capsules p.o. immediately. The employee should immediately |
|initiate first aid at the worksite by washing the contaminated skin with copious amounts of soap and water for 15 minutes. Eyes and mucous |
|membranes should be irrigated for 15 minutes with water or normal saline. |
| |
|Alternate treatment for significant exposures to MPTP analogues (e.g. 2’-CH2-MPTP or 2’=NH2-MPTP) is phenelzine sulfate (Nardil) 15 mg, four |
|tablets p.o. |
| |
|Report to UWMC or Harborview Emergency Room for medical examination, assessment, and further treatment as needed. |
| |
|NOTE: treat percutaneous exposures as low as 0.001mg/kg. Treat ingestion/mucosal exposures and inhalation exposures as low as 0.1mg/kg. |
|Consider treatment for any exposure especially if there is any burning or irritation at the site of exposure. |
| |
|Ongoing Post-Exposure treatment: |
|Selegiline 5 mg, #18, three (3) tablets twice each day for significant exposure to MPTP |
|Phenelzine sulfate 15 mg, #12, two (2) tablets twice each day is given for significant exposures to MPTP analogues (2’-CH2-MPTP or 2’-NH2-MPTP) |
|Follow up with EHC-UW and possible referral to neurologist |
