Making BUA personnel changes on the RSS app

May 1, 2025
Office of Environment, Health, and Safety

Previously, updates to personnel approved to conduct research on a BUA were made on Labs At Berkeley (L@B), the web application used to manage lab roster and training information. There is no longer a need to make BUA personnel changes in L@B. BUA personnel changes can now only be made in RSS BUA.

How do I make BUA personnel changes in RSS BUA?

Laboratory Safety Self-inspections

Each year, EH&S initiates and tracks the completion of lab safety self-inspections, which are conducted by principal investigators or their delegates. The topics covered are designed to supplement inspections conducted by EH&S in order to facilitate safety awareness and ownership within the lab.To promote this effort, please complete your self-inspection in advance of your General Lab Safety inspection. EH&S recommends you complete your self-inspection 3 to 6 months relative to the General Lab Safety inspection.

Fire Safety & Lab Doors: Propping Open Doors

Office of Environment, Health & Safety
2025

Many people prop doors open for ease of access or to increase airflow. However, not all doors are allowed to be propped open. Laboratory doors and any door opening into a corridor should never be propped open.

Access to many campus labs is restricted to approved personnel due to the presence of hazardous materials and equipment, including lasers, radiation sources, as well as biological and chemical agents. These areas require specific safety training and personal protective equipment (PPE) before entry is permitted. Any lab that handles...

Flooding Event and Improper Disposal of Glassware

March 6, 2025
Office of Environment, Health, and Safety
What happened?

Last month, severe flooding occurred in a campus building, leading to unexpected challenges in laboratory waste management.

A serious concern emerged when floodwater seeped into cardboard boxes, used for clean glass disposal, that did not have plastic liners. Without this essential barrier, the integrity of the boxes were compromised, rendering them unsafe for handling and disposal.

As a result, safety responders had to take extra precautions to safely transfer the broken glass and sharps to new disposal...

Electrical Fire Caused by Heat Gun Connected to Power Strip

What happened?

A small fire broke out in a laboratory in the Department of Physics when a service technician plugged a heat gun into a power strip that was plugged into an isolation transformer. When a transformer is overloaded, the transformer can experience high operating temperatures, causing it to overheat. In this case, the overheated transformer caused a small fire to break out.

Fortunately, there were no injuries and damage was very minimal. The service technician notified the lab manager as soon as they noticed smoke. The Lab Manager...
