The Occupational Safety and Health Act of 1970 states that, “the workers at the workplace should be provided with the safest working conditions”. OSHA works on two regulations, general and specific. This regulation applies on emergency eyewash and shower equipment.

The common requirements for urgent situation eyewash and shower equipment state the need of these equipments to be available at the work area for instantaneous emergency use. At the office, the workers are exposed to injurious caustic materials so there should be emergency eyewash and shower to facilitate workers for swift drenching or flushing of the eyes if some accident occurs.

The precise regulation is for convinced industries like telecommunication industry, paper-manufacturing industry, or other places where dangerous resources are being used. The two regulations, wide-ranging and specific, state as to where and when these emergency eye wash and shower equipment is required/available, nevertheless, it does not identify the installation set-up apparatus and smallest operating requirements. The America National Standards institute (ANSI) has provided the standard for working and installing these equipments.

The ANSI specifies the following standards for security equipments.

SHOWERS (Plumbed and Self-Contained)

Plumbed Shower

It is an urgent situation shower, which is linked permanently with a source of transportable water.

Self-Contained Shower:

As the name implies it has its individual flushing fluid that can be refill and replaced after employing.

The specifications for plumbed showers are as follows;

1. Heads

The head have got to be located 82″–96″ from floor. Similarly, there should be 20″ at 60″ diameter spray prototype above the floor. The flood rate also has specifications of 20 gallons per minute at 30 pounds per square inch. The scatter pattern should also be 16 inches away from any obstruction.

2. Valves

The valves must be activated within 1 second, and must not entail the use of hand to open them, still; they will stay ON until the user shuts it off.

3. Installation

The location of the shower must be not further than 10 seconds of reach, moreover should be sited at well-lit area. The shower should be celebrated with a warning and located at the same level as the hazard.

4. Maintenance and Training

The upholding of utensils is always obligatory, and the plumbed showers should be activated weekly to ensure proper and even working. The workers should be skilled to use these showers in case they are open to the elements of a chemical splash. The check of showers is also indispensable, and according to ANSI, a shower should be inspected annually.

EYE WASHES (Plumbed and Gravity-Feed)

Plumbed Eye Wash:

Parallel to plumbed shower wash, it is emergency eyewash, which is attached enduringly with a source of transportable water.

Gravity-Feed Eye Wash:

It is an eye wash that has its own flushing liquid that can be refilled with replaced subsequent to use.

The specification of eyewashes is pretty much similar to showers in terms of valves, installation, and maintenance & training; however, the heads must be positioned as ANSI standard for eyewashes.

EYE/FACE WASH

It is a machine used for double purposes to hose down and flush both the face and the eyes. The device also has stipulation standard for heads, valves, maintenance, plus guidance. All the specifications are same as showers excluding heads specification, which should be situated 33″–45″ from floor and 6″ from wall or nearest obstruction.

DRENCH HOSES

These hoses are used for multiple purposes to facilitate irrigation and flushing of eyes, face, and body areas in case of any mishap.
