Step 1 - Assess the risk
Safeguard your workers by predicting the severity of heat, flame or arc flash hazards, so you can assess and manage risk more effectively.
Heat and Flame Hazard
In many work environments, high temperatures and flames can pose a risk to employees, as can flammable materials, chemicals and gases. The ISO 11612 Standard lists a range of hazards against which there is a performance level to indicate if risk of exposure is low, medium or high. However, this should be treated only as a guide, a hazard assessment of a specific workplace should always be conducted to mitigate the hazards, reduce any risks and identify PPE requirements.
Electric Arc Hazard
Electrical arc is one of the most deadly and least understood hazards of electricity, and assessing for risk is essential to the wellbeing of electrical workers. A fundamental safety principle is to design out, eliminate or remove the hazard at its source. This means that the majority of electrical tasks must be carried out with the equipment made dead.
When equipment cannot be made dead for whatever reason, electrical arc can occur.
Hazard measurement and incident energy
The severity of the thermal effect of an arc flash is defined by the amount of incident energy that a victim, standing at a given distance away from the arc, could receive to the skin surface.
As detailed in our 4P methodology for Electric Arc Flash hazard and risk assessment, you need to be able to calculate incident energy to truly understand the risk. This is why we have included a useful tool to calculate incident energy to predict potential hazards and their severity.
Step 2 - Specify your fabric with Nomex®
A key part of the next step is to define the optimum PPE solutions to be used in any work environment and for the various different job roles. It is important to consider the layering of protective fabrics and garments; to understand everyday workwear requirements; and to review any additional protection which may be needed. Hand, face, eye and head protection must also be a considered.
Selecting and specifying the right fabric before choosing a garment supplier is essential.
An extensive portfolio of Nomex®-based fabrics is available to protect against heat, flame and electric arc effect; to suit all climates and many hazardous conditions. Nomex® garments are put to the test on a daily basis within dangerous work environments worldwide. With a track record for optimal performance, it’s a brand to be trusted.
