Storing Flammable Liquids in Refrigerators and Freezers

Flammable material refrigerators and freezers are designed to prevent ignition of flammable vapors inside the storage compartment and should be purchased whenever a refrigerator is needed to store flammable liquid. A flammable liquid is defined by the fire code as having a flash point of less than 100 ˚F (38˚C).

5.1 Flammables and Combustibles

GHS symbol showing a flame

Characteristics

These chemicals are easily ignited and may present a serious fire and explosion hazard. Flammable liquids have a flash point below 100°F. Combustible liquids have a flash point of 100°F to 200°F. Flammable solids have an ignition temperature below 212°F. Flammable solids include finely divided solid materials which, when dispersed in air, could ignite. Other...

Compressed Gas Cylinders: Proper Management And Use

Office of Environment, Health & Safety
2012

University of California, Berkeley (UC Berkeley) departments that use compressed gas cylinders must comply with a wide variety of laws and regulations, including those issued by Cal/OSHA, the California Fire Code and the City of Berkeley. This booklet provides general guidelines to help departments comply with those regulations. More specific information can be obtained from Material Safety Data Sheets and your department’s Job Safety Analyses (JSAs). Talk to your gas supplier about hands-on training and other useful safety information.

Compressed gas cylinders range from small...

Guide for Assembling a Pressure Vessel

Office of Environment, Health & Safety

This guide serves as an example and is presented with permission from LBNL. There are many types of pressure vessels so this serves as a template that allows you to replace the images to meet your specific needs.

Visual comparison guides are effective as a quick review of processes. It is recommended to keep these near relevant equipment. Visual guides can be useful for new researchers learning to use the equipment or as a refresher for those who do not regularly use the equipment. People may interpret qualitative descriptions differently so a visual guide helps to solve that...

Pressure Vessel Visual Inspection Guide

Office of Environment, Health & Safety

This guide serves as an example and is presented with permission from LBNL. There are many types of pressure vessels so this serves as a template that allows you to replace the images to meet your specific needs.

Visual comparison guides are effective for certain applications, when for example, researchers may otherwise not know what is acceptable or not. We might state “look for excessive wear or corrosion” but these are partly qualitative descriptions that people can interpret differently. Excessive wear to one person may not be the same to another. The visual guide helps to solve...

Principal Investigators

Principal Investigators (PIs) must ensure the safety of work assignments and work spaces, assign safety training related to hazards, provide safety procedures and equipment, correct identified hazards (where practicable), look into the causes of incidents and take action to prevent similar incidents, and discuss safety in regular meetings and performance reviews.

Personal Protective Equipment for Lab and Shops

Office of Environment, Health & Safety
2020

Controlling a hazard at its source is the best way to protect employees. Engineering or administrative controls to manage or eliminate hazards to workers is the preferred option. When engineering or administrative controls are not feasible or do not provide sufficient protection, supervisors must provide personal protective equipment (PPE) to their workers and ensure its use. Attire when occupying a laboratory or shop containing hazardous materials or equipment.

Lab Fire Caused By Hotplate Heating Oil Bath That Injured Researcher

March 31, 2013
What Happened?

A chemistry researcher was using an older model hot plate to heat an oil bath to 120-150°F. He borrowed the hotplate from someone else and was not familiar with the temperature controls. On this particular hot plate the temperature dial could go around from “LO” to “OFF” and back to “HI” heat. The researcher thought he had turned the hotplate “OFF” but it was still in the “ON” position and 30 minutes later the mineral oil bath ignited.

Fortunately, the oil bath was in a fume hood which kept the flames and fire inside the hood, it was reasonably clean and no other...

Biological Safety Program Manual

2026

UC Berkeley is committed to maintaining a healthy and safe workplace for all laboratory workers, students and visitors. This manual is an overview of the administrative steps necessary to obtain and maintain approval for the use of biological materials in laboratories, as well as a reference for good work practices and safe handling of other potentially infectious materials (OPIM).
