Protect your "Ice Sight”: The dangers of frozen eyewash stations
Winter is coming quickly which means so are freezing temperatures. Will your eyewash stations work when needed, or will they give workers the cold shoulder?
Which eyewashes and showers are most vulnerable?
Any outdoor eyewash or safety shower is vulnerable to freezing during the bitter cold. However, there are certain areas or environments that may be more susceptible to freezing including:
- Construction sites;
- Oil and gas pipeline service facilities;
- Chemical plants and oil refineries;
- Mining work sites;
- Agricultural facilities; and
- Areas exposed to high winds.
How can eyewash stations and safety showers be protected?
Whether plumbed or gravity fed, protecting this vital equipment from freezing can be accomplished through several different methods including:
- Investing in heated tanks, immersion heaters, or portable on-demand water heaters;
- Installing National Electrical Code (NEC)-compliant or electrical heat tracing around pipes and plumbing components;
- Covering gravity-fed stations with heated jackets;
- Providing freestanding, insulted units designed to maintain heat;
- Utilizing easy-to-remove covers or other protective features to protect against wind, ice and snow, and other winter debris; and
- Inspecting equipment more often to ensure it is operable throughout the cold season.
What do the standards say?
If drenching liquid or pipes are frozen, the ability to quickly use the equipment becomes an issue. OSHA’s Medical Services and First Aid regulation, 1910.151, requires employers to provide eyewash and safety showers where the eyes or body of a worker may be exposed to injurious corrosive materials. The standard states specifically that, “suitable facilities for quick drenching or flushing of the eyes and body shall be provided within the work area for immediate emergency use.”
Additionally, Section 4.5.5 of the American National Standards Institute (ANSI) Z358.1 requires that emergency showers are protected from freezing where this possibility exists. Otherwise, ANSI requires freeze-protected equipment to be installed. This is to ensure that there is a means for a minimum 15-minute flush of tepid (60–100° F) water in the event of an emergency.
Key to remember: Emergency eyewash stations and safety showers must be protected from freezing to ensure access to a minimum 15-minute flow of tepid water in an emergency, even during the coldest months of the year.
