The Differences Between EH (Electric Hazard) and SD (Static Dissipative)
Jun 29, 2023
In industrial settings, it is crucial to prioritize worker safety, particularly when it comes to electrical hazards and static electricity. Two commonly used terms in this context are EH (Electric Hazard) and SD (Static Dissipative). While they both relate to safety measures, they serve different purposes. In this blog post, we will delve into the distinctions between EH and SD and explore their respective applications and benefits.
EH (Electric Hazard):
EH, short for Electric Hazard, refers to a specific type of footwear that is designed to provide protection against electrical hazards. Electrical hazards include the risk of electric shock or electrocution. EH-rated footwear features specialized soles made of non-conductive materials, such as rubber or synthetic compounds, which act as insulators. These soles are intended to prevent the flow of electric current through the footwear and into the wearer's body. EH-rated footwear is primarily used in environments where workers are exposed to live electrical circuits or equipment.
Key Features and Benefits of EH-rated Footwear:
1. Non-conductive soles: EH-rated footwear ensures that electrical currents cannot pass through the footwear, reducing the risk of electric shock.
2. Insulation: EH-rated shoes act as a barrier between the wearer and the electrical source, providing protection against accidental contact with live circuits.
3. Compliance with safety standards: EH-rated footwear meets specific safety standards set by regulatory bodies to ensure the highest level of protection for workers.
SD (Static Dissipative):
SD, or Static Dissipative, refers to a different type of footwear designed to mitigate the risks associated with static electricity. Static electricity can build up on the body or clothing of workers, particularly in environments where there is a lot of friction or low humidity. SD-rated footwear incorporates special materials and designs that help dissipate static charges, preventing the accumulation of electrical potential on the wearer's body.
Key Features and Benefits of SD-rated Footwear:
1. Static charge dissipation: SD-rated footwear effectively dissipates static charges, reducing the risk of sparks or electrical discharges.
2. Protecting sensitive equipment: In industries where static-sensitive equipment or materials are handled, SD-rated footwear prevents electrostatic discharge (ESD) that could damage or destroy such equipment.
3. Enhanced safety: By preventing the buildup of static electricity, SD-rated footwear minimizes the risk of explosions or fires in environments with flammable substances.
EH vs. SD: Understanding the Differences:
While both EH and SD footwear aim to enhance worker safety, their primary focus differs. EH-rated footwear provides protection against electrical hazards, including the risk of electric shock or electrocution, by acting as an insulator against electric current. On the other hand, SD-rated footwear focuses on preventing static buildup and dissipating static charges to mitigate the risks associated with sparks or electrostatic discharges.
EH (Electric Hazard) and SD (Static Dissipative) are two distinct types of footwear designed to ensure worker safety in different contexts. EH-rated footwear safeguards against electrical hazards, while SD-rated footwear dissipates static charges. By understanding their differences and appropriate applications, employers can provide the necessary protection for their workers, reducing the risk of accidents, injuries, and damage to equipment. Prioritizing safety in the workplace is essential, and choosing the right footwear plays a significant role in achieving that goal.
