Categorizing clothes – bảo hộ lao động by design is mainly a means for describing what areas of the body the workwear item is intended to protect.
In emergency case, hazardous waste site cleanup, and dangerous chemical operations, the only acceptable types of protective uniforms – quan ao bao ho lao đong include fully or totally encapsulating suits and nonencapsulating or splash suits plus accessory clothing items such as chemically resistant gloves or boots. These descriptions apply to how the clothes – bao ho lao dong is designed and not to its performance.
The National Fire Protection Association has categorized clothes by their performance as:
a. Vapor-protective clothes provide gas-tight integrity and are intended for response situations where no chemical contact is allowable. This type of clothes would be equivalent to the clothing required in EPA’s Level A.
b. Liquid splash-protective clothes – bao ho lao dong offer protection against liquid chemicals in the form of splashes, but not against continuous liquid contact or chemical vapors or gases. Essentially, the type of clothes would meet the EPA Level B needs. It is important to note, however, that by wearing liquid splash-protective clothing, the wearer accepts exposure to chemical vapors or gases because this clothes – quần áo bảo hộ lao động does not offer gas-tight operations. The use of duct tape to seal clothing interfaces does not provide the type of wearer encapsulation necessary for protection against vapors or gases.
c. Support function safety clothes – Quần áo bảo hộ lao động must also provide liquid splash protection but offer limited physical protection. These clothes may comprise several separate protective clothing components ( coveralls, hoods, gloves- găng tay, and boots). They are intended for use in nonemergency, nonflammable situations where the chemical hazards have been completely characterized. Examples of support functions include proximity to chemical processes, decontamination, hazardous waste clean-up, and training. Support function protective clothes should not be used in chemical emergency case or in situations where chemical hazards remain undetermined.
d. These NFPA standards define minimum performance requirements for the manufacture of chemical protective clothes –quan ao bao ho lao dong. Each standard requires rigorous testing of the suit and the materials that comprise the suit in terms of overall protection, chemical resistance, and physical properties. Suits that are found compliant by an independent certification and testing organization may be labeled by the manufacturer as meeting the requirements of the respective NFPA standard. Manufacturers also have to supply documentation showing all test results and characteristics of their safety clothes.
e. Protective clothes – Quan ao bao ho lao dong should completely cover both the wearer and his or her breathing apparatus. In general, respiratory protective equipment is not designed to resist chemical contamination. Level A protection (vapor-protective suits) require this configuration. Level B ensembles may be configured either with the SCBA on the outside or inside. However, it is strongly recommended that the wearer’s respiratory equipment be worn inside the ensemble to prevent its failure and to reduce decontamination problems.
3. Life circle
a. Clothes – bảo hộ lao động item life circle is an end user decision depending on the costs and risks associated with clothes – bao ho lao dong decontamination and reuse. For example, a Saranex/Tyvek garment may be designed to be a coverall (covering the wearer’s torso, arms, and legs) intended for liquid splash protection, which is disposable after a single use.
b. Safety workwears –Quần áo bảo hộ lao động may be labeled as:
– Reusable, for multiple wearings
– Disposable, for one-time use.
The distinctions between these types of clothes –bảo hộ lao động are both vague and complicated. Disposable clothing is generally lightweight and inexpensive. Reusable clothing is often more rugged and costly. Nevertheless, extensive contamination of any garment may render it disposable. The basis of this classification really depends on the costs involved in purchasing, maintaining, and reusing protective clothes versus the alternative of disposal following exposure. If an end user can anticipate obtaining several uses out of a garment while still maintaining adequate protection from that garment at lower cost than its disposal, the suit becomes reusable. the key assumption in this determination is the viability of the garment following exposure. This issue is further discussed in the Paragraph on decontamination.
