Chemical Hygiene Plan & LATCH

A Chemical Hygiene Plan (CHP) is required per OSHA’s Occupational Exposure to Hazardous Chemicals in Laboratories standard (29 CFR 1910.1450) and Columbia University policy. The CHP provides essential information on prevention of potential exposures to hazardous materials and physical hazards in the laboratory.  Columbia University 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. 

The University’s CHP is managed by the Director of Occupational Health & Safety and can be found on the EH&S website.

Columbia University Chemical Hygiene Plan

The Laboratory Assessment Tool and Chemical Hygiene Plan (LATCH) is your laboratory-specific complement to the Columbia University Chemical Hygiene Plan. The LATCH identifies laboratory tasks and indicates the corresponding appropriate administrative and engineering controls, safety training, and personal protective equipment (PPE) needed to reduce potential exposures. 

The LATCH is managed and maintained by the each PI and/or laboratory.  EH&S has developed a comprehensive electronic database, the Laboratory Information Online Network (the LION) to manage the creation and maintenance of the LATCH.  The LATCH also includes information on staff training, emergency equipment and other laboratory assets and laboratory spaces under the management of each PI.

The LION system Tutorials: 

EH&S has developed a series of video tutorials to assist the research community with managing laboratory information in the LION.  Please see the links below for specific instructions on various LION functions.

LATCH – Begin or update a hazard assessment, add personnel and spaces, update training information
Corrective Actions – Respond to a corrective action notice following a laboratory survey
