Objective: Prevent and treat hazards from chemical skin irritants.

Trainer’s Note

Skin is a valuable body tissue; it must be protected from chemical irritants. For this module:

  • Review the information below on chemical irritants and their effects.
  • Ask workers to identify chemical irritants in their workplace.
  • Review the Personal Protection Equipment (PPE) workers should use.
  • Review the important points.
  • Have workers take the True/False quiz to check their learning.

Background

Different chemicals can irritate the skin. Some chemicals remove fats and oils from the skin. When this occurs, the skin becomes cracked and dry. Irritants can also cause severe burns. Or irritants can cause oils and waxes to plug hair follicles and sweat ducts. That can cause dermatitis and acne.

Types of irritants are shown below. The table also lists examples and effects.

Dermatitis

With dermatitis, the skin is inflamed and irritated. There are two types:

  • Primary irritation. Occurs from contact with a chemical irritant.
  • Sensitization. Skin becomes more sensitive after exposure. Then, just a small amount can cause a severe allergic reaction.

Adhesives
Paint remover
Disinfectants
Potassium hydroxide Disinfectants
Sterilizing agents
Strong solvents Dichloromethane
N-methylpyrrolidine
Paint remover
Alcohol
Prolonged dermatitis
Prolonged acne

Chemical Irritant Safety Practices

  • Identify hazards before working with chemicals.
  • Read the Safety Data Sheet (SDS) and labels on the containers.
  • Identify emergency procedures in case an accident occurs.
  • Avoid contact with strong chemical irritants.
  • Use PPE:
    • goggles
    • gloves
    • sleeves
    • aprons
    • shields
    • footwear
  • In case of exposure
    • use showers, eyewash fountains, hand/face spray units, and other emergency equipment
    • call 911 if appropriate
    • report accidental exposures to hazardous substance

Review These Important Points

  • Be aware of all types of skin irritants.
  • Know what substances you use that may be dangerous.
  • Follow the correct procedures in an emergency.
  • Wear protective equipment when on the job.
  • Use emergency equipment and call 911 if appropriate.
