Industry Group Profile - Lead Exposure. Inorganic lead is a malleable, blue-gray, heavy metal that occurs naturally in the Earthâs crust. Lead was one of the first metals used by humans and consequently, the cause of the first recorded occupational disease (lead colic in a 4th century BC metal worker).

Razor burn is a temporary skin irritation caused by shaving. Different people get razor burn for different reasons, but most of the time, it has to do with shaving too closely, too forcefully, or with a dull razor. It is usually identifiable by the itchy red bumps it leaves behind, and in most cases, only lasts for a few days.
After shaving, if redness or bumps are present, apply a warm washcloth to the skin for a few minutes to relieve irritation. Razor burn and bumps occur when excessive pressure or a dull razor is used. The skin is delicate, and scraping an object against it can cause irritation. Also, shaving against the direction of hair growth can lead to razor burn. Shaving with a dirty or old razor can also carry bacteria that inflames the skin when it is shaved.
