Is Your Lab Protected with an Environmental Safety Warning System?

Laboratory Safety

Many laboratories contain significant risks and the prevention of laboratory accidents requires great care and constant vigilance. Risk factors include high voltages, high and low pressure and temperatures, corrosive or toxic chemicals and vapors, radiation, and biohazards.

What is Laboratory Safety?

Measure to protect against laboratory accidents includes safety training and enforcement of laboratory safety policies, safety review of experimental designs and the use of protective equipment.

Depending upon the scientific research being conducted, it can fill a lab with dangerous chemicals, radioactive substances, biological specimens, sharp instruments, breakable glassware, and flammable objects. Thus, those working in labs need to be keenly aware of the many dangers associated with these items. In order to maintain a safe workplace and avoid accidents, lab safety symbols and signs need to be posted throughout the workplace.

OSHA Lab Standard


Requires that laboratory personnel implement appropriate control measures to ensure that exposures are as low as reasonably achievable.

In general, control processes can be categorized as administrative controls, engineering controls, standard operating procedural controls or personal protection.

Low Temperature

The low-temperature warning symbol warns staff of low temperature or cryogenic hazards in the lab. Such temperatures are usually much lower than freezing point.  They can be found in cold storage areas of the lab or where chemicals such as liquid nitrogen are stored.

Researchers, staff, and visitors should specifically note and understand the hazard communication information on the laboratory safety signs.  However, although the signs give the warning of what to be aware of when working it is easy to become involved in your work and be unaware of the dew point and lab temperatures.

Environmental Safety Warning System

PMC Therm-ALERT is a very flexible and customizable sensing and alarm system to warn employees and management when temperature or dew point in working areas reach dangerous levels.

The system comprises a high-performance capacitive humidity sensor with a temperature element, coupled to a display with one or more switch outputs to control functions such as warning lights. They mount the display within a NEMA 1 enclosure for indoor use or NEMA 4 for outdoors. The sensor installation can be within the main enclosure or in a separate remote enclosure with or without a secondary display.

How Can You Make It Suitable for Your Lab?

The PMC Therm-ALERT system is fully configurable to user needs, including:

  • Fully configurable to customer needs
  • Single warning light or multiple stack lights
  • Displays and annunciates Temperature, Dew Point, RH, or any combination
  • Customer programmable set points
  • Integral or remote sensors
