|Chemical protection and control|
|(Safety with chemical)
|You should know about chemicals.
· Some chemicals are easily flammable.
· Some chemicals can explode.
· Even without heat, chemicals with high concentrations can Volatile Causing the humidity in the surrounding atmosphere to increase And the surrounding atmosphere is less pure
· Excessive exposure to chemical vapors Causes irritation to the ears, eyes, nose, mouth, feeling abnormal in the stomach, the ability to work will be reduced.
· All chemicals can cause severe irritation. If it splashes in your eyes Especially hot chemicals But it’s still less dangerous than driving in the midst Busy traffic
· The safety level of the chemical must comply with Set standard values
· Safety standards help everyone do their jobs safely.
· To be healthy and safe at work must Relying on cooperation from those who are involved It is also the responsibility of the management to comply with the safety standards.
· Should monitor the working environment. To make sure that there is no danger to the health of the workers. And keep a record of the results
· Give advice to the workers about Hazardous chemicals used in the workplace
· Provide the workplace to be safe. There is a problem in the work area, notify your boss immediately.
· If you think that operations are not safe Can ask for cooperation in the health hazard assessment from Related departments
· Strictly follow the rules of operation Must work with care and Practitioners must be well trained.
· Follow the safety rules at all times.
· If you need more information or have problems, consult your supervisor. Or officials from government agencies Related to safety
The constituent elements of the hazardous chemical toxicity depend on
· Individual receiver sensitivity
· Nutritional status
· Duration of exposure
· Geographical factors, such as exposure to heat, are increasingly dangerous.
Chemicals enter the body by
· Way of breathing
· By eating
· Skin contact
· Through the placenta from mother to child
Chemical toxicity Can be divided into groups as follows
· Substances that cause irritation, itching, burning, blistering, such as acids, chlorine gas, ammonia, sulfur dioxide.
· Substances that cause unconsciousness This chemical replaces oxygen such as carbon dioxide, nitrogen, cyanide.
· Narcotic substances are substances that are harmful to the nervous system, such as volatile substances such as alcohol, benzene, acetone, ether, chloroform, causing headache, dizziness and dizziness.
· Substances that are harmful to the blood formation system, such as lead, are used to suppress the bone marrow. Which serves to make red blood cells Making less red blood cells than normal, causing anemia
· Substances harmful to bones Deforming the bones Or makes phosphorus calcium brittle bones
· Substances that harm the respiratory system, such as the lungs, cause membranes. Cannot be exchanged with oxygen The air capacity in the lungs is less, it is easy to suffocate, such as sand, coal dust.
· Mutant Harm the chromosomes. The anomalies can be seen in the offspring or offspring, such as radioactive substances, insecticides, some metals, some drugs.
· Carcinogens make new cells more and more. More than necessary Cause unnecessary tumors such as radioactive substances, arsenic, asbastos, nickle, vanil chloride, benzene.
· Chemicals that cause infant disability The birth is not complete organs such as cleft lip, cleft palate, amputated arm. Examples of substances in this group are thalidomide, some solvent Some pesticides
Chemicals ordered to use Should be labeled as follows:
· Trade name
· Chemical name
· Name and address of the manufacturer and distributor
· Danger symbol
· Risk nature
· Safety advice
In addition, the company Material safety data should be offered.
· Chemical name
· Harm to the body and health
· Entrance to the body
· Monitoring the health of workers
· Levels that allow exposure
· Precautions for use
· Safety and operational controls
· Personal hazard equipment
· Code of Practice for a Leak
· Emergency measures
· First aid
· Other resources
Master in the control and prevention of chemical hazards, chemical
· Use less toxic substances instead.
· Change the production process, such as using a wet system instead of a dry one. So as not to cause dust to spread
· Separate hazardous production processes
· Create a cover for the production process completely. Not allowing chemicals to spread out
· Install a local exhaust system
· Machine tool maintenance
· Maintaining a clean and tidy workplace
· Installation of a general ventilation system
· Increase the distance to the operator from the source of the chemical.
· The detection of chemical content against the safety standard values must be improved. Correct if it exceeds the safety standard.
· Dangers education and training and prevention
· Reduction in working hours involving hazardous chemicals
· Rotation or shuffle of duties
· Having operators work in specially controlled rooms
· Health check before going to work
· Using personal protective equipment
· Must be aware of the hazards of chemicals and control methods.
· Always wash your hands after working with chemicals.
· Always wear personal protective equipment.
· Clean the work area every time after work.
· Keep the container tightly closed after every use.
· do not! Using a chemical mouth instead of a rubber ball
· Keep chemicals in a cool place. Good ventilation Away from the source of ignition
· do not! Working alone or without involvement
· do not! Test by inhalation or ingestion.
