What is a laboratory certificate of fitness?

A laboratory certificate of fitness is issued by the New York City Fire Department to laboratory users. The certificate of fitness ensures personnel qualified to act during a fire emergency are available inside laboratories while it is operating. See the laboratory certificate of fitness page for more information.

Who needs a laboratory certificate of fitness?

At any time a laboratory is in operation, a certificate of fitness holder must be present. If someone works over the weekend, that person must have a certificate of fitness. If the certificate of fitness holder leaves for lunch, all lab operations must cease if no certificate of fitness holder is present. For these reasons Environmental Health and Safety recommends every person working in a laboratory maintain a certificate of fitness. See the laboratory certificate of fitness page for more information.
