The ACS Committee on Chemical Safety has developed a website with a collection of methods and tools for assessing hazards in research laboratories. The tool is based on the committee's publication "Identifying & Evaluating Hazards in Research Laboratories."From the website:

Safety in the laboratory requires a full team effort to be successful. When everyone in the laboratory understands how to identify hazards, assess risk, and select the appropriate control measures to eliminate a hazard or minimize risk, accidents, injuries and near misses can be reduced.

THE FOLLOWING INFORMATION WILL:
Familiarize you with the fundamentals of hazard assessment;
Guide you through preparation practices such as scoping and assembling your team;
Offer a number of ways to conduct hazard assessments;
Provide tools (e.g., templates, examples, etc.) that can be shared with your team and used immediately.
