What chemicals require emergency shower?

OSHA requires eye/face washes and showers when working with or around corrosive chemicals, or equipment that can contain corrosive chemicals, such as:

  • Anhydrous ammonia.
  • Formaldehyde.
  • Open surface tanks.
  • Forklifts and other powered industrial trucks.
  • Telecommunications batteries.
  • Paper and pulp-making equipment.

Under what two circumstances should you use the safety shower?

Emergency showers and eyewash stations are a necessary backup to minimize the effects of accident exposure to chemicals. Emergency showers can also be used effectively in extinguishing clothing fires or for flushing contaminants off clothing.

Do eyewash stations need tempered water?

What temperature should the water be? The 2014 ANSI standard recommends that the water should be “tepid” and defines this temperature as being between 16-38°C (60-100°F). Temperatures higher than 38°C (100°F) are harmful to the eyes and can enhance chemical interaction with the skin and eyes.

How often should safety showers be checked?

Accordingly, emergency showers and eyewashes are required by the ANSI/ISEA Z358. 1-2014 Standard to be activated weekly, with a more thorough evaluation on an annual basis. This requirement is established in Sections including 4.6.

What are the requirements for safety showers and eyewash stations?

Requirements for both Both safety showers and eyewash stations must be able to provide the recommended flow for at least 15 minutes. This usually translates into having the equipment plumbed in with hard connections to the water supply. For example, a quick calculation for the safety shower at 20 gpm yields 300 gallons needed.

What is the ANSI standard for emergency safety showers?

The ANSI standard details installation requirements for emergency showers and eye wash stations. The location of emergency safety showers must be on the same level as the potential hazard requiring their use. They must be free from obstructions and well-lit with clear signage to make it easy for people to find.

What is the minimum flow rate for a safety shower?

Safety shower flow rates must meet the need for sufficient flow of water to flush the affected area completely. Showers require a minimum supply of 20 gallons per minute at a pressure of 30 lbs. per square inch for at least 15 minutes. Eye washes require a minimum flow rate of 0.4 gallons per minute.
