Tales from the Toolbox

Mineral Oil

Having worked for many years in the engineering trade I have had to conform to rules and regulations regarding health and safety, from the correct operation and use of breathing equipment in poisonous or explosive atmospheres to the correct use of a bench grinder, but no one seems bothered about the thousands of DIY mechanics who risk their health every time they perform repairs or service to their motor vehicles. I have therefore dragged out my files and found a cautionary notice from the Heath and Safety Executive and have re-typed it below. The idea behind this is to get the budding mechanics out there to stop and think about what they are working with, for example when draining the engine oil could a pair of rubber gloves be used when handling the oil?  

There are many other dangers when working on motor vehicles. The notice below is aimed at engineering workshops but most of it applies to general areas of Health and Safety when handling mineral oils.  

Effects Of Mineral Oil On The Skin.

The term Mineral Oil is intended to include a wide range of hydrocarbon fractions from light oils such as kerosene and gas oils, to the heavier fuel and lubricating oils. The effects of mineral oils on the skin vary according to the duration of exposure and to the type and grade of oil used. 

Skin Rashes.

Oil acne is recognised by the presence of blackheads, pimples and pustules. The arms are most often affected, but the rash may occur on any part of the body where there is contact with oil or oily clothing. Fuel oils, such as diesel oils are known to cause dermatitis. The lighter fractions also remove the protective grease normally present on the surface of the skin. This renders the skin dry, liable to crack and more prone to damage caused by cuts and abrasions due to metal swarf and also to irritant chemicals.

Skin Cancer.

Prolonged exposure to certain mineral oils, eg used engine oils, may lead to the development of warty swellings or sores, which are slow to heal and which may be cancerous. These may occur on the scrotum in particular. Delay in seeking treatment may be fatal.

Precautions.

Avoid as far as possible any skin contact with mineral oil or with clothing contaminated with mineral oil.

Before Work.

 1          Put on and carefully adjust any protective clothing that is provided. Change and clean all work clothes (including protective clothing) at least once a week. Dry cleaning is necessary to remove mineral oil from clothing.

2          Use suitable barrier creams, which may give some protection against mineral oil and assist the cleaning of the skin after work. Lanolin based hand creams are usually very effective. Re-apply before work is resumed after each break.

At Work.

 1          Make full use of protective devices such as splash guards.

2          Take care to prevent ordinary clothes, especially underwear, from becoming contaminated with oil.

3          Do not put oily rags or tools in pockets, especially trouser pockets.

4          Examine your skin, particularly your scrotum, each time you bath or shower.

5          Remove metal particles and swarf from machines with the implements provided.

6          Have first aid treatment at once for any injury, however slight.

After Work.

1          Make regular use of washing facilities, including baths, to ensure that all oil is removed from the skin. Having washed with soap, rinse repeatedly with water until the skin is clean. Dry carefully.

2          Skin cleansers may help in the removal of mineral oil.

3          Use of conditioning cream after washing helps to counter de-greasing of the skin.

Action.

Seek immediate medical attention for any rash, wart or sore developing on any part of the body, particularly the scrotum.
