Choosing the right disposable protective coverall is now more important than ever, and while we recommend looking at detailed product literature on what the coverall will and will not protect you against, there are some basic things to consider.

As a guide only, the process of choosing the right coverall starts with answering various questions about contaminants (hazardous or not) and work environments. Many factors can lead to different coveralls for the same application or job. We recommend considering the below steps before you choose your protective coverall:


Step 1: Conduct a detailed assessment of the work environment and the nature of the hazards including consideration of the following:

  • Physical state of contaminant
  • Form of contaminant (chemical concentration/particle size)
  • Type of exposure
  • Working environment (temperature, humidity)
  • What kind of job is going to be performed
  • What other PPE will be used with the coverall
  • Additional risks (for example: electrostatic charge, infective agents, nuclear particles)


Step 2: Determine the degree of exposure and minimum levels of protection needed.

Based on the level of protection they provide, disposable coveralls are classified into six categories (opens new tab).

 

Step 3: Assess Hazard Toxicity, and short-term and long-term exposure.

Consider if the protective coverall has been tested against a given hazard and how it performs. Also refer to permeation data of a coverall which means that the coverall was tested against a specific hazard/toxic substance. Not all coveralls are the same, even if they are the same “type”. It is all about how it performs against a given hazard or chemical substance.

 

Step 4: Consider the comfort of the wearer.

Most Type 5/6 protective coveralls are made from either SMS (Spunbond Meltblown Spunbond fabric) or Microporous material, and although they both offer the same protection level, selection may differ in terms of comfort, breathability and even application. For example, SMS fabric generally is more breathable than other coverall fabrics and may be more suitable in hotter environments. MP, or microporous laminated coveralls on the other hand, may provide a more suitable barrier to liquid splashes as it offers higher tensile strength and a more effective liquid barrier as a result.

 

Step 5: Ensure proper training - on how to don, adjust, and remove a protective coverall is provided to wearers.


Step 6: Fit Test. All PPE should be fit tested for size and its effectiveness to protect the wearer.

 

Note: If unsure, it is important to discuss your protection requirements with a product expert prior to purchasing disposable coveralls, as statutory and/or regulatory requirements may apply in your workplace.
