For example, the following warning is found on the MSDS for Clorox
®
bleach:
DANGER: CORROSIVE. May cause severe irritation or damage to eyes and
skin. Vapor or mist may irritate. Harmful if swallowed. Keep out of reach of children.
Some clinical reports suggest a low potential for sensitization upon exaggerated
exposure to sodium hypochlorite if skin damage (e.g., irritation) occurs during
exposure. Under normal consumer use conditions the likelihood of any adverse
health effects are low.
Medical conditions that may be aggravated by exposure to high concentrations
of vapor or mist: heart conditions or chronic respiratory problems such as asthma,
emphysema, chronic bronchitis or obstructive lung disease.
