What does level of protection type 3/4 and 5/6 mean?

The level of protection provided by a garment is an important consideration when selecting protective clothing. The level of protection is often measured by the type of hazard that the garment is intended to protect the wearer from. Common hazards that protective clothing guards against include chemical, biological, and radioactive contamination, as well as fire and other physical hazards.

There are six primary types of protective clothing levels -  type 1 to type 6. Type 1 provides the highest level of protection against known hazards, while type 3/4 and 5/6 offer varying degrees of protection depending on the specific hazard.

Type 3/4 protective coverall offers limited protection against liquid splashes. This type of protective clothing is typically used for tasks that involve occasional splashes, such as cleaning up small spills, maintenance work, or chemical handling. The level of protection offered by type 3/4 protective clothing is determined by the material used to create the garment, which must be resistant to penetration by liquids and hazardous materials.

Type 5/6 protective coverall is designed to provide greater protection against hazardous substances compared to type 3/4. This type of protective clothing is typically used in situations where the potential for exposure to hazardous materials is high, such as during chemical spills or cleaning contaminated areas. Type 5/6 clothing provides greater protection against both liquid and solid particulate hazards, and is typically made from materials such as laminated fabric, which are highly resistant to penetration.

Garments rated TYPE 3/4 and 5/6 are typically disposable and are used to protect against specific hazards for limited periods of time. They are often worn over clothing to create a suitable barrier against liquid and solid particulate hazards.

The choice of protective clothing is dictated by the level of risk posed by the specific task. Protective clothing must offer the necessary level of protection required, which may be determined by conducting a risk assessment of the environment or substances involved. In many cases, protective clothing will be required to comply with local standards and regulations.

Chemical protective clothing must be designed to provide protection against specific chemicals. In order to achieve this, protective clothing is often tested and rated based on how well it protects against a particular chemical. Protective clothing that achieves a rating of Level A, B, C, or D provides different levels of protection against various hazardous chemicals.

When working with chemicals, solid particulate matter, or liquids, protective clothing is essential to ensure the safety and well-being of workers. Type 3/4 and 5/6 protective clothing offers varying degrees of protection against different hazards, and is often made from materials that are highly resistant to penetration. When choosing protective clothing, it is important to consider the specific hazards involved, as well as the level of risk posed by the task.

The choice of protective clothing is vital to ensure the safety and well-being of workers, and must be based on the level of risk posed by the task.
