Hand protection Chemical-resistant, impervious gloves complying with an approved standard should be
worn at all times when handling chemical products if a risk assessment indicates this is
necessary. Considering the parameters specified by the glove manufacturer, check
during use that the gloves are still retaining their protective properties. It should be
noted that the time to breakthrough for any glove material may be different for different
glove manufacturers. In the case of mixtures, consisting of several substances, the
protection time of the gloves cannot be accurately estimated.
Safety eyewear complying with an approved standard should be used when a risk
assessment indicates this is necessary to avoid exposure to liquid splashes, mists,
gases or dusts. If contact is possible, the following protection should be worn, unless
the assessment indicates a higher degree of protection: chemical splash goggles and/
or face shield. If inhalation hazards exist, a full-face respirator may be required instead.

Information on toxicological effects
Classification
Styrene manufacturers have determined that the weight of evidence for the
carcinogenicity of this substance does not meet the criteria for classification.
In 2018, styrene was listed by IARC as a probable carcinogen to humans (Group 2A)
based on hazard assessment data. The United States NTP listed styrene as reasonably
anticipated to be a human carcinogen based on "limited evidence" from studies in
humans, "sufficient evidence" from studies in experimental animals, and supporting data
on mechanisms of carcinogenesis. The significance of these results for humans has not
been established through risk assessment.
