SAFETY CONSIDERATION:
Planning safety is a very important aspect to be considered in the planning of setting up of a plant. The safety precautions taken by the management would lead to a better working by the labour since they would not have to worry about their safety (Ref) Safety planning can be classified as
a) Identification of hazardous operations.
b) Prevention and control of possible hazard which can be ensured by setting up various alarms and trip devices.
The Benzaldehyde is relatively non-toxic material.The registry of Toxic Effects of Chemicals (NIOSH) lists the following data for benzaldehyde. LD 50 (orl-rat) 1300 mg/kg. LD 50 (orl-guinea pig) 1000 mg/kg.
Benzaldehyde is considered a moderately toxic substance when ingested. Benzaldehyde should be handled with the good manufacturing practices of avoidance of contact, adequate ventilation, and cleanliness normally accorded the handling of solvents and other organic compounds. Prolonged exposure to the vapors of benzaldehyde should be avoided. At temp of less than 250C, saturates mixtures of air and benzaldehyde will contain less than 950 ppm benzaldehyde.
Contact with the skin and eyes should be avoided. Direct contact with benzaldehyde may cause dermatitis. For chemical workers, goggles, gloves, and face shields are recommended. In the event of skin contact, the skin should be washed with soap and water. Call a physician if irritation develops. In the event of eye contact, plush the eyes for 15 minutes with large amount of water. Get immediate medical attention.
Benzaldehyde has a low ignition temperature 1920C (3780F). Therefore benzaldehyde should be kept away from areas of high temp, such as uncovered steam and hot oil lines. Rags used to wipe up spills of benzaldehyde and activated carbon used to absorb vapors of benzaldehyde care must be taken when disposing of these materials (REF).
