DIFFERENT STEPS ON CHEMICAL SAFETY CONTROL

ENGINEERING CONTROLS
• Substitution of a less toxic materials
• Change in process to minimize contact with hazardous chemicals
• Isolation or enclosure of a process or operation
• Use of wet methods to reduce generation of dusts or other particulates
• General dilution ventilation
• Local exhaust, including the use of fume hoods

WORK PRACTICE AND ADMINISTRATIVE CONTROL
• Good practices can help to reduce the risk of exposure to chemicals
• Administrative controls involves rotating job assignments and adjusting work schedules so that workers are not over exposed to a hazardous chemical

USE OF PERSONAL PROTECTIVE EQUIPMENTS
• Safety goggles
• Face shields/ mask
• Protective clothing and foot wear
• Gloves

SAFE WORK PRACTICES AND PROCEDURES FOR FLAMMABLE AND COMBUSTIBLE LIQUIDS AND SOLID
Flammable and combustible liquids – vaporize and form flammable mixtures with air when open containers, when leak occurs or when heated.
STORAGE OF FLAMMABLE AND COMBISTIBLE LIQUIDS
• Flammable and combustible liquids should be stored only approved containers. A safety can is an approved container of not more than 5 gallons capacity that has a spring closing lid and spout cover.
• Flammable liquid storage cabinet is an approved cabinet that has been designed and constructed to protect the contents from external fire.
Storage cabinets must also be conspicuously labeled.
• Handling precautions the main objectives in workings safety with flammable liquids is to avoid accumulation of vapors and to control source of ignition
• Flammable aerosols
Flammable liquids in pressurized containers may rapture and aerosolize when expose to heat, creating a highly flammable vapor cloud as with flammable liquids, these should be stored in a flammable storage cabinet.
• Flammable and combustible solid
Many flammable solids react with water and cannot be extinguished with conventional dry chemical or carbon dioxide extinguishers.
 Ensure class “D” extinguishers where flammable solids are used or stored.
 Sand can usually be used to smother a fire involving flammable solids keep a container of sand near the area.
