The Hazmat Team shift is one of the most unpredictable special events in Animal Hospital. Instead of a normal workday, the hospital becomes covered in green slime while a dangerous Anomaly named Slimebert begins wandering the halls.
Although this event only lasts for a single shift, it can quickly become overwhelming if you aren’t prepared. In this guide, you’ll learn when the Hazmat Team event appears, how to complete the shift successfully, the best way to deal with Slimebert, and several tips that can make the entire encounter much easier.
When Does the Hazmat Team Shift Appear?
The Hazmat Team event typically occurs between Shift 12 and Shift 17, though most players report encountering it around Shift 15. The exact shift number isn’t fixed, so don’t expect it to appear at the same point during every playthrough.
You’ll know the event is about to begin after a short story sequence featuring Dr. Harlow. During this scene, he leaves the hospital to meet members of the Animal Corporation Hazmat Team outside. After speaking with them briefly and telling them to use the back entrance next time, he returns inside.
Moments later, the hospital fills with green gas, slime spreads throughout the building, and the Hazmat Team officially begins their cleanup operation.
Since this event only lasts for one shift, your objective is to finish it before Slimebert becomes increasingly difficult to avoid.
What Happens During the Hazmat Team Shift?
Once the event starts, several Hazmat workers enter the hospital carrying specialized cleaning equipment. They’ll patrol the building while vacuuming up slime that has spread across the floors. Unfortunately, the slime isn’t the only problem you’ll face.
Shortly after the shift begins, a giant slime creature known as Slimebert arrives as a patient. Unlike regular patients, Slimebert doesn’t wait for treatment. Instead, he freely roams the hospital, leaving slime behind and actively chasing players. Touching Slimebert causes him to swallow your character. While this doesn’t instantly eliminate you, it creates several problems:
- You lose valuable time.
- Your Sanity meter decreases.
- Patient management becomes more difficult.
Your main objective remains unchanged despite the chaos. Continue checking in patients and completing treatments before the shift timer expires.
How to Deal with Slimebert
Slimebert cannot be defeated permanently during the Hazmat Team shift, but you can temporarily stop him using a Fire Extinguisher. Spraying Slimebert knocks him backward, creating enough space to safely move past him or escape if he’s blocking your route.
However, this effect is only temporary. After a short delay, he’ll recover and continue roaming the hospital. Rather than trying to eliminate him repeatedly, use the Fire Extinguisher only when necessary. The best strategy is to:
- Spray Slimebert if he blocks a hallway or doorway.
- Create enough space to continue your task.
- Ignore him afterward and return to treating patients.
The quicker you finish the shift, the less opportunity Slimebert has to interfere.
Best Tips for Completing the Hazmat Team Shift
Surviving this event is much easier with the right strategy. These tips can help you complete the shift more consistently.
Use the Firefighter Class
The Firefighter class is one of the strongest choices for this event. Unlike the standard Fire Extinguisher, the Firefighter’s version automatically recharges over time and doesn’t require refill stations. This gives you more opportunities to push Slimebert away whenever he gets too close.
The class also provides immunity to Sanity loss caused by fire hazards, making it especially useful during later shifts when multiple environmental dangers begin stacking together.
Reach the Event Quickly
Before the Hazmat Team appears, focus on clearing the early shifts as efficiently as possible. Rather than aiming for perfect patient scores, prioritize finishing check-ins and treatments quickly. The sooner you reach the later shifts, the less time you’ll spend repeating earlier sections if a run goes wrong.
Don’t Waste Time Chasing Slimebert
Although it may be tempting to keep knocking Slimebert down, doing so usually slows your progress. Remember that the event ends by completing patient objectives—not by defeating the Anomaly. If Slimebert isn’t directly preventing you from reaching a patient or workstation, simply avoid him and continue working. Only use the Fire Extinguisher when you absolutely need to create an opening.
Plan Your Route
Since Slimebert constantly patrols the hospital, avoid repeatedly running across the entire building. Whenever possible:
- Complete nearby patients before moving to another area.
- Watch Slimebert’s movement before entering narrow hallways.
- Keep an escape route in mind if he suddenly changes direction.
Good positioning can save more time than repeatedly stopping to use your Fire Extinguisher.
Is the Firefighter Class Worth Using?
If you’re expecting to encounter the Hazmat Team event, the Firefighter class is one of the safest picks available. Its enhanced Fire Extinguisher offers greater convenience thanks to automatic recharging, allowing you to respond to Slimebert without worrying about running out of charges. While other classes remain perfectly viable, the Firefighter provides several advantages that directly counter the hazards introduced during this special shift.
The Hazmat Team shift transforms an ordinary hospital day into one of Animal Hospital’s most challenging events. Between the spreading slime, roaming Hazmat workers, and the constant threat of Slimebert, every second counts. Fortunately, understanding how the event works makes it much easier to survive. Keep a Fire Extinguisher ready, avoid unnecessary fights with Slimebert, and focus on completing patient treatments as quickly as possible. With the right approach, you’ll clear the Hazmat Team shift and continue your run without letting the slime slow you down.
