What does NFPA say about labeling?
National Fire Protection Association Labeling
NFPA uses a symbol system designed as a diamond-shaped label containing four differently colored squares. A number (0-4) or an abbreviation is added to each square indicating the order of hazard severity. The higher the number, the greater the hazard.
Is the NFPA diamond on SDS?
While NFPA codes cover several aspects of flammable materials pertinent to SDS’s, perhaps the most significant is the NFPA 704 Hazard Identification ratings system (the familiar NFPA “hazard diamond” shown on the right) for health, flammability, and instability.
How often should fire hoses be inspected?
every three years
In addition to the annual inspection, the fire hose needs to be tested every three years, with the first time being 5 years after the manufacturing date. This test is referred to as the Hose Pressure Service Test. A fire safety professional can take care of this for you along with annual inspections.
When should fire hose be inspected?
Hose that is in service should be service tested at least annually. Hose held in storage for longer than 1 year shall be service tested before being placed into service.
What pressure do you test fire hose at?
200 psi
Supply fire hose shall be service tested to a minimum of 200 psi (13.8 bar or 1380 kPa) or a pressure not to exceed the service test pressure marked on the hose.
