Coveralls are essential workwear for professionals in a variety of industries, and they come in various types, including the Type 4 and Type 5 coveralls. They offer excellent protection to workers against hazardous materials, chemicals, and other harmful substances. However, it is essential to understand the differences between the two types of coveralls to make an informed decision when choosing the appropriate workwear for your job.
Type 4 Coveralls
Type 4 coveralls are made of synthetic fabrics such as polypropylene, polyethylene, or a combination of both. They are designed to provide protection against liquid chemicals and hazardous substances that can cause harm to the skin. These coveralls have a taped or sealed seam that makes them completely impermeable, preventing any harmful liquids from penetrating the fabric. Type 4 coveralls are commonly used in industries such as pharmaceuticals, chemical manufacturing, and laboratories, where workers are exposed to hazardous chemicals.
These coveralls come with an elastic waist, cuffs, and ankles, ensuring the suit fits properly, preventing any gaps. They are also available in different styles and sizes to cater to the needs of different workers. The design also includes a low linting feature, which ensures they eliminate dust, reducing the risks of contamination in sterile environments.
Type 5 Coveralls
Type 5 coveralls are made of high-density polyethylene fabric and are designed to protect against hazardous substances such as asbestos, dust, and particles. The fabric is also treated with antistatic properties, which is an effective solution against static electricity, which can cause sparks and eventual explosions in explosive environments.
Type 5 coveralls come with a sewn-in crotch gusset and a two-way zip to provide the worker with better mobility and access to pockets. Like Type 4 coveralls, they also come with an elastic waist, cuffs, and ankles to provide a better seal against hazardous substances.
The Differences between Type 4 and Type 5 Coveralls
One of the most significant differences between Type 4 and Type 5 coveralls is the materials used to manufacture them. While both coveralls protect workers from hazardous substances, Type 4 coveralls are designed to protect against liquid chemicals, while Type 5 coveralls protect against dust and particles.
Another significant difference between the two types of coveralls is the seams. Type 4 coveralls have sealed seams to prevent liquid chemicals from penetrating the fabric. In contrast, Type 5 coveralls have sewn-in seams.
Type 5 coveralls come with a two-way zip and a sewn-in crotch gusset, providing workers with better mobility and access to pockets. Type 4 coveralls don’t have these features as the impermeable fabric required on Type 4 coveralls can be challenging to sew and would cause seams to be weak spots.
When to Use Type 4 or Type 5 Coveralls?
As mentioned earlier, Type 4 coveralls are suitable for industries such as chemical manufacturing, pharmaceuticals, and laboratories, where workers are exposed to hazardous chemicals. These coveralls are imperative in preventing any harmful liquid materials from penetrating and coming in contact with the worker’s skin.
On the other hand, Type 5 coveralls are ideal for workers who deal with dust and particles, such as asbestos handling and construction workers. These coveralls protect workers’ skin and respiratory systems from hazardous particles and dust, making them essential workwear in such industries.
Conclusion
Both Type 4 and Type 5 coveralls are essential workwear in various industries, providing workers with the necessary protection against harmful substances. Understanding the differences between the two coveralls is vital in choosing the appropriate workwear for the job. Type 4 coveralls offer better protection against liquid chemicals, while Type 5 coveralls protect workers against dust and particles. Always choose the appropriate coveralls that meet the demands of the job for the best protection.
