I accidentally caused a fire in my department laboratory. The fire was not big, and luckily no one was injured. However, it triggered the fire alarm and sprinkler system, which led to some of the common equipment being damaged.
After the incident, the department has enforced tighter control on lab safety. For example, all students need to submit a work flow before doing new experiments and complete numerous forms to buy new chemicals. It results in a lot of unnecessary administrative work and greatly slows down our research progress. Many research students are unhappy about that, and since I caused the accident, they have begun to ostracize me. Even some 'closer' students seem becoming less friendly to me.
I know it is totally my fault, but sadly, I already caused the accident and can do nothing to change the fact. Now the problem is, what should I do to mend my relationships with my colleagues?
EDIT: As some of the comments mentioned that it is not clear whether the additional rules actually should be enforced no matter there was the accident or not. Honestly, I don't know, but it is the extra work that annoy other students, and it is totally because of me. I guess my department should have complied to the laws before, otherwise they will be in trouble...
