High Hazard Chemicals
At LSU, the safe management of high hazard chemicals is a critical priority to ensure the safety of all personnel and the surrounding community. High hazard chemicals include substances that are classified as select carcinogens, reproductive or developmental toxins, and chemicals with high acute toxicity. Due to the increased risks associated with these materials, strict protocols must be followed for their handling, storage, and disposal.
Definition of High Hazard Chemicals
High hazard chemicals include:
- Select carcinogens: Chemicals known to cause cancer in humans.
- Reproductive or developmental toxins: Chemicals that can impair human reproduction or cause developmental issues.
- Chemicals with high acute toxicity: Substances that pose significant risk through short-term exposure, even in small quantities.

Training Requirements
Laboratory personnel who work with high hazard chemicals are required to complete mandatory training programs. This training will ensure that staff are knowledgeable in:
- Understanding and interpreting Safety Data Sheets (SDS) for chemicals in use.
- Selecting and using appropriate personal protective equipment (PPE).
- Correctly implementing decontamination, spill response, and waste disposal protocols.
Training is a vital component of our commitment to maintaining a safe research environment. EHS offers periodic training sessions, and records of completed training must be kept for compliance.

Personal Protective Equipment (PPE)
When working with high hazard chemicals, appropriate personal protective equipment (PPE) must be worn at all times. This includes:
Safety goggles or face shields to protect eyes and face.
Laboratory coats and gloves appropriate for the chemicals being handled.
Respirators, if necessary, based on the chemical’s hazards and the lab environment.
Make sure that PPE is selected based on the chemical’s risks and that all personnel
have been trained in its use. If respirators are required, individuals must receive
medical clearance before use.
Waste Disposal Procedures
Proper disposal of high hazard chemicals is essential to maintaining a safe environment and regulatory compliance. To ensure safe disposal practices, we highly recommend reviewing the Chemical Waste Disposal section of our website.
Chemical Hygiene Plan
A Chemical Hygiene Plan (CHP) is required per OSHA’s Occupational Exposure to Hazardous Chemicals in Laboratories standard (29 CFR 1910.1450) and LSU policy. The CHP provides essential information for prevention of potential exposures to hazardous materials and physical hazards in the laboratory. LSU has developed a Chemical Hygiene Plan to provide an overview of information about the use of hazardous materials in research laboratories, their hazards, warning signs, control measures, safety training to minimize exposure and waste management.
Emergency Procedures
In the event of a spill, exposure, or other emergencies involving high hazard chemicals, immediate action is required. All personnel should:
- Evacuate the affected area if necessary and follow emergency response procedures.
- Use spill kits and decontamination procedures as outlined in the lab’s SOPs.
- Contact LSU’s emergency response team and EHS for further support.
