Irritant electronics industry

Oils and coolants have recently been reported as common irritants in the electronics industry [20]. This problem has not been previously highlighted. In the paper quoted, however, the precise chemical culprits are not given. Historically, exposure to oil-based cutting fluids have been considered to be associated with cutaneous squamous cell carcinomata [42, 43], although no reports of this have as yet emerged among workers in the electronics industry.

Stabilized by resonance with the aromatic ring (Scheme 9.11). Hydrolysis of these side-chain halides is generally easy, especially if there is an electron-withdrawing substituent in the ring. Many are lachrymatory, contact of the vapour with moisture on the eye resulting in hydrolysis and liberation of HX. This irritates the eye and tears are produced. An industrial route to benzaldehyde from toluene involves hydrolysis of the intermediate product PhCHCl2.

Propylene oxide is an allergic and irritant agent, used as a solvent and raw material in the chemical industry as starting material and intermediate for a broad spectrum of polymers. It can be used as a dehydrating agent for the preparation of slides in electron microscopy. Occupational dermatitis was also reported while using a skin disinfectant swab.
