Title Protecting Workers in California from Dermal Exposure to Hazardous Chemicals
Introduction LA Testing provides industrial hygiene and environmental testing services, sampling supplies, monitoring instruments and personal protective equipment to identify and mitigate occupational exposure risks.

Huntington Beach, CA, September 25, 2023

The National Institute for Occupational Safety and Health (NIOSH) estimates that more than 13 million workers in the United States are potentially exposed to chemicals that can be absorbed through the skin. Dermal exposure to hazardous agents can result in a variety of occupational diseases and disorders, including occupational skin diseases (OSD) and systemic toxicity.

Occupational skin diseases are in fact the second most common type of occupational disease reports NIOSH. They can occur in several different forms, including:

  • Irritant contact dermatitis
  • Allergic contact dermatitis
  • Skin cancers
  • Skin infections
  • Skin injuries
  • Other miscellaneous skin diseases

The Occupational Safety and Health Administration (OSHA) also warns that skin exposure to chemicals in the workplace is a significant problem and states:

Most chemicals are readily absorbed through the skin and can cause other health effects and/or contribute to the dose absorbed by inhalation of the chemical from the air. Many studies indicate that absorption of chemicals through the skin can occur without being noticed by the worker. In many cases, skin is a more significant route of exposure than the lung. This is particularly true for non-volatile chemicals which are relatively toxic and which remain on work surfaces for long periods of time.

“Contact dermatitis is one of the most common types of occupational illness, with estimated costs exceeding $1 billion annually from just that one skin condition according to NIOSH,” said Michael Chapman, Laboratory Manager at LA Testing’s Huntington Beach facility. “In California, LA Testing’s industrial hygiene and environmental laboratory specialists identify occupational exposure risks to chemicals that could be dermal and respiratory threats. In addition to laboratory testing services, we also offer sampling supplies, air monitoring instruments and a full line of personal protective equipment (PPE) to help protect against inhalation and direct contact hazards.”

Last year, LA Testing sponsored an educational video about dermal exposure to chemical hazards in the workplace that can be seen at:
