Newer heat trace units incorporate stainless steel eyewash bowls with covers to protect the unit from wind, rain, and snow. Emergency signaling alarms connected to heat trace units will send immediate alerts to co-workers and first responders about the incident. These alarms can also be connect- ed to building systems for remote monitor- ing. Look for systems that meet the NEMA 4X standard and are certified to ANSI/ISEA Z358.1 and cULus requirements.
Enclosed safety showers come as com- plete packages offering an enclosed shelter from the elements, privacy, and a warm ambient environment. These showers can withstand seismic activity, hurricane-force winds, and highly corrosive environments in petrochemical facilities, oil and gas re- fineries, nuclear and power plants, mines, and other industrial applications.
These freestanding units are insulated to keep the internal temperature warm down to -25° F (-32° C), making them ideal for sub-zero applications. Several units will require a plumbed water supply; however, there are also self-contained units that will require only a full tank of water and a con- stant power source.
Portable gravity fed units are ideal for work environments in which plumbed water is not available. These convenient systems incorporate water tanks that pro- vide adequate water volume to complete a full 15-minute flush at the ANSI-mandated flow rate. Some units are designed with hinged eyewash trays that may be activated in one quick motion, while stainless steel clamp mechanisms secure the tank during transport.
Custom designed solutions may be re- quired for challenging applications that re- quire more complex and flexible emergen- cy shower or tepid water systems. Variables such as facility size and spatial configura- tions, plumbing requirements and special needs, and goals and budgets undoubtedly make each application unique.
