Lab Hazard Assessment Tool (LHAT)

Login to Laboratory Hazard Assessment Tool (LHAT) at

The new Laboratory Hazard Assessment Tool (LHAT) has been created as part of the University of California’s commitment to continuing a culture of safety. LHAT is a web-based system intended to identify and communicate hazards present in a lab or research area. Once hazards are identified, staff can take appropriate Personal Protective Equipment (PPE) training and print a voucher that can be used for procurement. LHAT will be used by all academic appointees, staff, students, and visitors to prevent workplace illnesses and injuries.

As a Principal Investigator (PI), LHAT allows you to:

  • Identify or add lab workers into their lab group
  • Determine hazards that are present in the lab through guided questions
  • Communicate laboratory hazards to personnel through the LHAT
  • Identify the proper PPE to be used based on the hazard assessment

As Laboratory Personnel, LHAT allows you to:

  • Identify with a lab group
  • View potential hazards present in the lab through the assessment
  • Receive a list of proper PPE to be used in your lab setting
  • Receive training & demonstrate understanding of the training on the selected PPE for your lab
