APPENDIX 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 various items of protective wear to safeguard your own health. 3. Maintain scrupulous cleanlines at all times. Thoroughly wash hands and feet before taking meals. It is essential to take a bath before leaving the factory. 4. Wash off any chemical falling on your body with soap and water. If splashed 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. 7. Keep your food and drinks away from work place. Consuming food, drinks or tobacco in any form at the place of work is prohibited. 8. Serious effects from work with toxic chemicals may follow after any years.
