p-Chlorophenyl isocyanate

Made for specialty chemical manufacturing and used in research/production; releases can occur during manufacturing, mixing, or spills [1][3].

Mostly at work by breathing vapors/aerosols or via skin contact; the public is rarely exposed except near industrial sites or accidents [1][2].

Causes burning eyes/skin, cough, wheeze, and chest tightness; can “sensitize” you so later tiny amounts trigger asthma; high exposures can injure lungs [1][2].

Chemical plant and lab workers handling isocyanates; applicators of isocyanate-containing coatings; people with asthma/allergies; workers without good ventilation or PPE [1][2].

Use closed systems and local exhaust; wear chemical-resistant gloves, goggles, and protective clothing; use NIOSH-approved respirators when needed; get training, air monitoring, and medical surveillance; follow community alerts during incidents [1][2][3].
