WHAT ARE ELECTRICAL HAZARD RATED SAFETY BOOTS?
Electrical hazard (EH) rated safety boots are ISOLATING safety boots meaning they provide a secondary source of protection for you from electric shocks or electrocution. The idea behind these EH rated safety boots is pretty simple, the entire surface of the boot is made from non-conductive materials and as a result no electrical charge will pass through the body, because you are fully isolated from the ground. EH rated safety boots have an Electrical Hazard (EH) rating on them, meaning they have been tested by the American Society for Testing and Materials (ASTM) for their protection against an electrical shock.
PROTECT YOURSELF FROM ELECTRICAL HAZARDS
Protection from electrocution or any other electrical hazard can be obtained in many ways. One of the most direct and efficient features to prevent electrical hazard is the use of insulating protective equipment inside safety boots.

HEALTH RISKS FROM ELECTRIC CONTACT
Electrocutions are one of the most frequent electrical hazards in construction sites. When in direct contact with electric high voltage equipment, such as overhead powerlines or transformer cabins, electrocution can be fatal by cardiac arrest. Each year they cause more than 300 deaths and 4,000 injuries. Electricity flows through conductors including metals, water, earth, but also the human body. When electrical equipment is functioning properly, the circuit is maintained between the tool, the wires and the electric source.
However, in case of a malfunctioning machine or circuit, the operator can become part of the electric circuit. When in direct contact with a “live” wire, a person can feel a tingling sensation, over an intense electric shock, to ultimately a fatal electrocution, depending on the power, frequency and type (AC/DC) of electric source. Voltages over 50V AC or 120V DC are considered hazardous.
slight, not painful but disturbing shock
painful shock, loss of muscular control
freezing current, muscular contraction, but can also be pushed away from the circuit
50 - 150 mA
extreme pain, severe muscular contraction, respiratory arrest, death is possible
1.000 - 4.300 mA
heart fibrillation, muscular contraction and nerve damage, death is likely
severe burns, cardiac arrest, death is probable
Electric contact can occur in many ways and situations, we listed the most common below:
