7 things to know about substitutions of substances

Working with substitution and phasing out dangerous chemicals is a continuous task and an important one. Not everybody knows how to conduct it efficiently. Learn more about the process and start substituting today. 

To be able to perform a chemical substitution in an effective manner, it is helpful to learn more about the topic. By using a step by step method on how to substitute, it will become easier to begin the process of using less dangerous chemicals at your workplace. After testing this method, you will learn what works best for your company and how to establish a procedure that you and your colleagues can use.  

  1. Determine hazards and assess risks. 

This step involves choosing whether the present product or process is a hazard. What products are on-site? Is there a substantial risk associated with storing, using, or taking care of a product? To answer these concerns, make sure to have a precise inventory of all products, as much information as possible regarding each product, including technical information, quantities, and life-cycle considerations (use, storage space, dealing with, transportation, and disposal). Identify if any of the products (or their active ingredients) are recognised on a regulative checklist as toxic, prohibited, toxic, etc. (for example, the Domestic Substance List under the Canadian Environmental Protection Act).

  1. Identifying alternatives

Explore a variety of alternatives. Compare every one of the hazard assessment information.

  • Will the substitute product satisfy the technical needs (e.g., solubility, drying out time, etc.)?
  • Compare the various states of a chemical (e.g., will a granular kind develop less dust than a powder type?).
  • Is the product compatible with the process, various other products, or the equipment?
  • Is the job needed or otherwise (e.g., can the part be changed rather than cleaned)?
  • Do existing control approaches properly regulate the substitute (e.g., a much less hazardous substitute may vaporise a lot more quickly, and the existing airflow system may not sufficiently capture the vapours)?
  • Will the existing waste disposal system meet technical and regulatory requirements when using the substitute when managing any new waste produced?
  1.  Complete the hazard assessment and think of what can occur if used alternatives.

You must gather all available and make a reasonable comparison of both the positive and negative points.

  • Picking an alternative product may require changes in:
  • The method the work is done,
  • How and where the product will certainly be used,
  • Who will certainly be affected or revealed,
  • The amount utilised,
  • The sort of equipment or components (e.g., O-rings, gaskets, or hose materials) required to be compatible with the substitute,
  • The airflow system that may be required,
  • The disposal methods and regulatory requirements that may be used.
  1. Comparing options. 

In this action, compare the various other choices and the substance or process presently being used. It can be difficult to compare the risks of one eruptive chemical with a very harmful one. Think of the impacts in basic terms, such as "Is the substitute most likely to take off or toxin people? Will it just affect people who work with it, or could it impact other individuals in the location?" Bear in mind to consider exactly how and where the choice will be used.

  1. Choosing whether to substitute.

First, it is good to introduce the substitute on a trial or small quantity basis. This step is the most difficult.Remember that a change in one phase of a process can affect many others. Please consult with the workers handling the product directly for their input.

  1. Presenting the substitute.

Strategy the modification in material or process thoroughly. Remember to train and enlighten the workers included.

  1. Analysing the modification. 

Check to see if the substitution has actually created the desired outcomes. You may discover checking the workers' health and wellness, keeping track of the level of impurities in the air, or satisfying legal needs for functional parameters to measure.
