MEDTECS - SAFEGUARDING EVERY TOMORROW
Coveralls are loose-fitting garments that cover the whole body except for the head, hands, and feet. Coveralls are commonly made from high-density polyethylene (HDPE) formed into a non-woven fabric that allows heat and sweat to leave the suit while preventing liquids and aerosols from entering it.
DETAILS MATTER- ESPECIALLY HEALTH WORKERS
The interfaces on the suit, including the zipper, cuffs, and the edge of the hood or collar, are made liquid-tight to prevent leakage. Cuffs, hood and collar interfaces can be elastic or liquid-tight seals. In addition, the zipper area can have fabric flaps that cover them or be specially made as liquid-tight zipper assemblies.
The sewing of coveralls can be the most difficult part to get right. Seams are sealed by putting tape on them for protection strengthen purposes. However, places, where multiple seams join (such as the armpit), can be difficult to seal properly. Medtecs, in another hand, has been manufacturing coverall for years, we make sure that hospitals workers can have the best protection in the market.
■ EU standard
Standard EN ISO 13688 specifies general performance requirements for ergonomics, innocuousness, size designation, ageing, compatibility and marking of protective clothing and the information to be supplied by the manufacturer with the protective clothing. The regulation further specifies the coveralls into 6 types.
- Type 1: Gas Tight Suits (EN 943 part 1) – Protects against liquid and gaseous chemicals.
- Type 2: Non-gas Tight Suits (EN 943 part 1) – Protects against liquid and gaseous chemicals.
- Type 3: Liquid Tight Suits. (EN 14605) – Protects against liquid chemicals for a limited period.
- Type 4: Spray Tight Suits (EN 14605) – Protects against liquid chemicals for a limited period.
- Type 5: Particulate suits (EN ISO 13982-1) – Protects against airborne dry particulates for a limited period.
- Type 6: Reduced Spray Tight Suits (EN 13034) – Protects against a light spray of liquid chemicals.
■ Taiwan standard
Standard CNS 14798 classifies coveralls into P1, P2, and P3 levels based on the requirements of disposable medical coveralls test (CNS14798 T5019). The test includes ultimate tensile strength, burst strength, suture strength, tear resistance, moisture permeability, hydrostatic pressure, impact penetration, sub-micron particulate filtration efficiency, synthetic blood penetration, and bacteriophage penetration.
- P1 level: Hydrostatic pressure and impact penetration are two main test items. P1 level coverall prevents the patient’s blood and body fluids from splashing onto other people.
- P2 level: Emphasis on preventing the clothing from fracturing, tearing, and rupturing due to tensile force and expansion. Especially the seams on coveralls.
- P3 level: Compare to P2 level, P3 level doesn’t test sub-micron particulate filtration efficiency, but it tests synthetic blood and bacteriophage penetration. Waterproof tape is usually added to the seams to prevent blood or body fluids from leaking through.
