APPENDIX-A

CAUTIONARY PLACARD/NOTICE

Carcinogenic dye intermediates

1. Dye intermediates which are nitro amino derivatives or aromatic hydrocarbons

are toxic. You have to handle these chemicals frequently in this factory.

2. Use the variousitems of protective wear to safeguard your own health.

3. Maintainscrupulous cleanliness at all times.Thoroughly wash hands and feet

before taking meals. It is essential to take a bath before leaving the factory.

with a solution of the chemical, remove the contaminated clothing

immediately. These chemicals are known to produce cyanosis. Contact the

medical officer or appointed doctor immediately and get his advice.

5. Handle the dye intermediates only with long handled scoops, never with bare

hands.

6. Alcoholic drinks should be avoided as they enhance the risk of poisoning by

the chemicals.
