Wayne State University Department of Chemistry Laboratory Hazard Assessment Checklist This form is a modified version of the Laboratory Hazard Assessment Tool (LHAT) developed by UCLA’s Office of Environment, Health and Safety (http://www.ehs.ucla.edu ). It should be completed for each research laboratory in the Department of Chemistry at Wayne State University by the faculty member responsible for that facility. The checklist should also be completed for each undergraduate level laboratory class in chemistry by a faculty member teaching the class. The tool identifies hazards to employees and students and specifies personal protective equipment (PPE) to protect employees and students during lab activities. Date: Course: Person(s) Completing Form: Room(s) where laboratory experiments are prepared and/or conducted: The OSHA Laboratory Standard 29 CFR 1910.1450 and the MIOSHA Standard 1212 part 431 both require employers to provide employees with information and training to ensure that they are apprised of the hazards present in their work area. Use of appropriate PPE is required at Wayne State University when working with hazardous materials as stated in the university’s Chemical Hygiene Plan. http://research.wayne.edu/oehs/pdf/chemical-hygiene-plan.pdf “Personal protective equipment (PPE) shall be used as necessary to augment the protection provided by engineering controls, experiment design, standard operating procedures, and good work practices. PPE should not be used as the primary means of controlling hazardous chemical exposure! Selection of PPE shall take into account a variety of factors including the identification of the hazard and task-specific conditions, the routes of exposure (inhalation, skin absorption, eye or skin contact, and/or ingestion), and the performance of the PPE material in providing a barrier to these hazards.” (Section 11, page 19) “All other personal protective equipment such as face shields, lab coats, shoe covers, etc. specified by the Principal Investigator must be used as directed.” (Section 11, page 20) “PPE such as laboratory coats must be removed immediately upon significant contamination.” (Section 11, page 20) “Laboratory workers should know the location and proper use of personal PPE, including lab coats, gloves, and eye protection”. (Section 9.b, page 18) Version 2, 12/16/16 Chemical Hazards (See WSU Chemical Hygiene Plan for additional information on policies related to these materials) YES NO Question Activity Potential Hazard Recommended PPE C01 Working with small volumes (<4 Eye or skin damage.
