Prevention of dermatitis
If, as we have seen, dermatitis is an allergic reaction to one or more substances, than the obvious way to avoid it is to identify the offending (or potentially offending) substance and make sure that there is no contact with it.
Beware of the most common offenders
Take a look at the list of substances identified above and make sure that you are using protection to avoid contact with these substances (always wear gloves when handling these substances, for example).
Read the labels and the MSDS sheets for all substances that you handle on a regular basics
Not all offending substances are going to be labeled as such so it is up to you to make sure that you do the research. Go online and see if others have developed allergic reactions to the substances that you are using. Call and ask the manufacturer for the MSDS sheets for them (many are available online).
Replace where possible
If you are consistently using one of the substances known to cause contact dermatitis, try to find other ways of doing the job; find less hazardous substances. If there is no alternative, try changing the schedule to reduce the time of exposure, enclose the process or automate it where possible.
Wear protective equipment
Non-latex gloves, tyvek protective clothing, eyewear, etc… are all designed specifically to protect the user from the substances that might harm them. Take time to find out which ones work best for the particular substance(s) that you are working with. There are numerous different types of gloves, for example (nitrile, vinyl, neoprene, viton, etc…) and all react differently and/or have a different “break-through” time. Charts are available that show the different breakthrough and degradation of each type of glove to the specific substance(s) you are coming in contact with. Clean or replace these gloves and protective clothing regularly.
Wash, dry and moisturize often
Wash your hands regularly, dry completely and moisturize to make sure that you are protecting against the loss of oils. Make sure, however, that the soap and moisturizer that you are using aren’t the cause of the dermatitis. Use barrier cream to protect hands.
Check your skin regularly
The earlier you identify it the easier it’s going to be to deal with.
