Chemical and Liquid Jet Resistant Coverall for Industrial Protective Clothing

Industrial protective clothing is an essential compromise between eliminating potential risks and completing the tasks while accepting certain harms that are inherent in daily working life. Even for a skilled worker, instead of periled his life to hazardous working environments, choosing suitable industrial protective clothing is a must to prevent fatal incidents.

 

Health effects of chemical exposure

There are few statistics or case reports arise from chemical exposures in industrial workplace. According to statements released by Health and Safety Executive (HSE) in United Kingdom, cases of occupational ill health continue to rise as about 99% of work-related deaths each year were associated with exposure to chemicals. Out of this data, major deaths arose from cancers and chronic obstructive pulmonary disease (COPD). A total of 13,000 deaths each year are industrial work-related lung disease and cancer attributed to past chemical exposures.

 

Besides, studies from U.S. Bureau of Labor Statistics shown that exposure to harmful substances or environments is among the 5 most common causes of workplace fatalities, with nearly 10 percent of all workers who lose their lives due to occupational illnesses or injuries succumb to chemical exposure without proper industrial protective clothing. This amounts to an estimated top 60,000 deaths out of roughly 860,000 illnesses resulting from chemical exposure in the industrial workplace every year.

 

Chemical and liquid jet in the industrial workplace

While we often think of chemicals as something created in a laboratory, chemicals can be naturally occurring or mixed with other compounds by manufacturing methods, either in solid, liquid, or gaseous state. Some of the most common chemical exposure risks include aluminum, asbestos (http://www.derekduck.com/page/196), benzene, lead, mercury, petroleum, pesticides and silica. These dangerous chemicals can be present everywhere from hospitals and offices to construction sites and other locations out of the mentioned industrial fields.

 

Most chemicals are harmless unless they enter your body, but unfortunately there are many routes by which a chemical can in contact with you easily, such as ingestion, absorption, inhalation and penetration. There are two primary types of chemical exposure normally occur in workplace, namely dermal exposure and inhalation. Each of these can be a risk under different work scenarios, and each carries its own set of dangers. For dermal exposure, industrial protective clothing complies with Category III (http://www.derekduck.com/page/29) which against chemical and liquid jet might be an alternative protective clothing for workers. Type 3 certification on liquid tight suits is the suitable protective clothing which can protect against strong and directional jets of a liquid chemical such as spray from a burst pipe under pressure, with a barrier fabric and sealed seams.

 

A liquid jet can be referred as a stream of fluid that is projected into a surrounding medium, usually from nozzle, aperture or orifice. Jets can travel long distances without dissipating as it has higher momentum compared to the surrounding fluid medium. Thus, for Type 3, EN 17491-3 Jet Test is normally used as a determination of resistance to penetration by a jet of liquid. The principle of Jet Test is a water jet with fluorescent or visible dye tracer being directed under controlled conditions at industrial protective clothing worn by a human test subject. The result of the test will be determined by a calibration stain area, which is the stain area produced by 0.02ml of the test liquid. If any penetration is greater than 3 times compared to the total calibration stain area, it fails. The test is strictly repeated on 3 suits, and all 3 pieces must pass to be certified.

 

Criteria of suitable industrial protective clothing

Scientific experts believe that harmful chemicals and substances in the workplace are ultimately responsible for a significantly larger number of chronic illnesses and deaths that got untracked because the symptoms do not typically appear suddenly, but rather over the course of years. Thus, the industrial protective clothing that is selected must be resistant to permeation, degradation, and penetration by the respective chemicals or hazards it will be exposed to. For example, through checking on the chemical permeation (http://www.derekduck.com/page/215) test result of the technical data sheet offered from manufacturers, it is possible to evaluate the chemical resistance of the protective clothing.

 

Permeation is the process when a potential hazard chemical passes through a material on a molecular diffusion. Although there aren't any holes visible to naked eyes, there are still possibilities for chemical molecules to permeate through the fabric. There are two crucial parameters namely Permeation rate (PR) and Breakthrough time (BT) which help on classifying the protection level of the sample fabric. PR indicates the mass of the chemical in micrograms, which can be transferred through µg/cm2/min, while BT is the elapsed time between first exposure of the fabric to chemical and the rate of permeation reaching a target value. When measured according to a standard method, the performance of the breakthrough time is a value by which different fabrics can be equitably compared.

 

ULTITEC 4000 as effective protection shield for industrial purposes

This fully liquid-proof protective clothing provides an effective shield against various chemicals, liquid jets, infective agents and leaking fuel. Few standardized tests on fabric physical properties, fabric chemical properties, against infective agents with EN 14126 have been tested on this industrial protective clothing. Among all strict performance examination, ULTITEC 4000 managed to reach repellency of Class 3 for both sulphuric acid and sodium hydroxide with optimal fits design features (http://www.derekduck.com/page/93 ).

There are some considerable features on protective clothing ULTITEC 4000 (http://www.derekduck.com/page/133):

Conclusion

In order to fulfil chemical and liquid jet resistant protective clothing, several tests have been strictly carried out, such as industrial protective clothing ULTITEC 4000 has been proven to be hold out more chemical substance according to EN374-3 test method (http://www.derekduck.com/page/192), and ULTITEC 5000 is also qualified with CE certification Type 3, 4, 5 protective clothing. With these fabric and seam technology against chemical and liquid jet, industrial protective clothing series of ULTITEC 4000 is most well applied in petrochemical industry, as recently there are overwhelming achievements that shared by global partners from Philippines and Malaysia, which include supplying ULTITEC 1000L to Shell Philippines in 2017, also ULTITEC 4000 is approved and win the tender to be applied in PETRONAS oil company in Malaysia. Besides, due to positive feedbacks gained from Germany A+A Show for ULTITEC 5000, this newly launched protective clothing of Type 3 will be shown in Dubai INTERSEC in coming future as high-level chemical and liquid jet resistant coverall for industrial protective clothing.
