Product information Safety emergency showers

Reliable help in emergencies

In the "event of an emergency", the reliable, immediate and compliant water delivery of a safety emergency shower is indispensable. These elementary requirements are of course the basis of the development of the NovaLab safety emergency showers. We take into account the known microbiological requirements for products in contact with (drinking) water.

Key product features:

Reliability and robustness

• Emergency shower heads are made of solid brass and provided with an additional corrosion protection layer. Reliable even in the event of a fire.
• Valve technology proven for years.
• Water-bearing components and trigger construction made of corrosion-resistant stainless steel or brass. The surface is high-quality electrostatic powder-coated.
• All NovaLab safety emergency showers are sealable to reduce the risk of misuse.

Standards and regulations: core requirements

NovaLab safety emergency showers meet the requirements of the following standards and regulations.

• DIN EN 15154 Parts 1 and 2: Safety Emergency Showers – Body and Eye Showers
  Among other things, the standard sets requirements for the volume flow, water distribution and shut-off behaviour.
• TRGS 526: Technical Rules for Hazardous Substances
  The Technical Rules for Hazardous Substances of the Federal Institute for Occupational Safety and Health are to be applied to laboratories. The volume flow rate for body showers is prescribed at least 30 l/min.
• BGI/GUV-I 850-0: Safe Working in Laboratories – Basics and Guidelines
  The regulation of the German Social Accident Insurance under the auspices of the German Employers' Liability Insurance Association for the Chemical Industry is to be regarded as a nationally applicable set of rules in accordance with DIN EN 15154. According to this, a volume flow rate of 30 l/min is sufficient for body showers and the supply via a pipe separator or free outlet is permitted.

Microbiology and drinking water

In order to take into account the growing requirements regarding the microbiological behaviour of drinking water installations, the (further) development of the NovaLab safety emergency showers was carried out taking into account the relevant standards and regulations (DIN, DVGW, VDE, etc.).

In concrete terms, this means:

• No stagnation volume on the outlet side due to complete automatic emptying of the shower arm and
  -through specially developed geometry - of the emergency shower head.
• Avoid plastic components in contact with (drinking) water as far as possible.
• Small cable diameter for the connecting cable possible.
  Because NovaLab body showers achieve the minimum volume flow of 30 l/min at only approx. 1 bar flow pressure, the connecting pipes can be dimensioned correspondingly small. In this way, NovaLab body showers contribute to reducing the (stagnation) volume in the connecting pipes.
• If larger volume flows are desired, body showers are available, which release approx. 60 l/min of water at 1.5 bar flow pressure.
• All NovaLab body showers can be equipped in such a way that they can be operated "loop-through", i.e. without a separate branch line (on request).

Further planning and operating information

• From any location in the laboratory, a body shower should be carried out within a maximum of 5 sec. can be reached.
• Tempering the water to temperatures above room temperature is not suitable because of the risk of contamination.
• Distance from switches and sockets: The size of the spray area should be assumed to be at least the size of the water cone of the body shower for the wetted surface according to DIN EN 15154 Part 1.
• Body and eye washes must be checked for functionality at least once a month.
