But we think the real solution is to control the mist. Outbreaks of dermatitis usually involve dry, cracked, scaly skin, pimples on the arms and hands, and raw sores. Workers performing the same operation and using the same types of coolants can have totally different reactions to machining fluids, and conditions may differ dramatically between different coolant systems. Second, anti-corrosion, germicidal and other additives in the machining fluids can irritate and sensitize the skin. Third, contaminants in the cutting fluids, like suspended particles or metal shavings, can scratch or cut the skin.
Harmful bacteria can then infect the cuts.
Find out if other workers have had the same symptoms. More than one other person with the same problem is very strong evidence of a workplace cause. If it's a union workplace, ask your health and safety representative to investigate. To play it safe, follow work restrictions recommended by your doctor. HP must be diagnosed early before irreversible damage is done.
