  1. 1. Prepared by:ANAND RAJ
  2. 2. Pesticide is a substance meant for attracting, seducing, destroying any pest.  Classification of pesticides: • • • • • • (a) Herbicides – which kill plants. (b) Insecticides – which kill insects. (C) Fungicides – which kill fungi. (d) Bactericides – which kill bacteria. (e) Piscicides – which kill fish. (f) Rodenticides – which kill rodents.
  3. 3. Inhalation of pesticides.  Adverse working environment.  Pest attack.  Dangerous manual handling operations.  Fire and explosion. 
  4. 4. Mention detail of pesticides in registers.  MSDS of pesticides.  Labelling of pesticides.  Training.  Hierarchy of control.  Health checkup facility.  Safety in manual handling operations.  Routes of entry of pesticides into the body.  Safety in storage of pesticides.  Safety in transportation of pesticides. 
  5. 5. Safety during leakage and spillage.  Safety during fires.  First aid procedures.  Personal protective equipment. 
  6. 6. All pesticides kept on the premises or used in the workplace must be named in register.  A register contain: • • • A list of all pesticides stored, used, transported or handled. MSDS of all pesticides. An indication of assessments for each pesticides.
  7. 7. Employer must obtain current MSDS for all pesticides used or stored in the workplace.  MSDS must be: • • • • Readily available to the employees who may be exposed to the substances. Not more than 5 years old. Used in training. Used for information about the substances for risk assessment.
  8. 8. Pesticides must be labelled correctly.  It must contain: • • • • • • • Brand, chemical, common names. Formulation, ingredients & contents. Directions for use. Storage and disposal information. Environmental hazards. First aid information. Manufacturer information.
  9. 9. Employers must provide training to employees.  It must be provided on: • • • • • • Potential health risk and toxic effects. Control measures. Correct use of control methods. Correct care and use of PPE & clothing. Need and details of health check up. MSDS.
  10. 10.  Prevent exposure by:- • Elimination of hazardous substances. Replacement of the hazardous substance by less hazardous one. Isolation of hazardous substance. Reorganizing work to reduce exposure time. • • •  Reduce • • • exposure by:- Engineering controls such as blowers and ventilation. Administrative controls. PPE.
  11. 11.  Employers must provide health checkup facility at workplace where • the health of person is at risk of exposure to substances. the workplace risk assessment identifies a person as being exposed. •  Employers must provide health checkup facility at least once per year for workers who regularly exposed to chemicals.
  12. 12. Use suitable containers to carry the equipment and pesticides.  Using handcarts.  Lifting heavy object by more than one worker.  Lifting heavy object with correct posture. 
  13. 13. Through skin: Safety precautions: • • • Avoid coming into direct skin contact with pesticides. Not wear clothing contaminated with pesticides. Avoid exposure to pesticide droplets or vapors. Through mouth: Safety precautions: • • One should not drink, eat or smoke until having cleaned their hands and faces. One should avoid contamination of food by pesticides.
  14. 14. Through inhalation: Safety precautions: • • • Maintain good ventilation. Use protective respirators properly. Prevent pesticides from spreading through ventilation system.
  15. 15.        Keep pesticides in closed area, so that leaks & spills cannot contaminate surrounding areas. Store pesticides in original containers only, making sure labels are protected and readable. Keep PPE near the storage facility so that it can be accessed easily for use in the event of a spill or accident. Keep a spill kit and absorbent material close to the pesticides storage location. Do not store volatile or reactive products together. Good ventilation is to be provided. Store pesticides away from water.
  16. 16. Must have safely stacked on the vehicle.  Must be transported by appropriately instructed and trained operator.  Always check product labels to ensure they are present and intact.  Carry PPE in the vehicle including gloves to deal with spill in transit.  Do not leave loaded vehicle unlocked and unattended.  Do not load damaged or leaked containers.  Vehicle must carry fire extinguisher, emergency plan.  Vehicle must be provided with warning signs. 
  17. 17. Evacuate non-essential persons from the area of spillage immediately.  Wear protective clothing and equipment.  Take immediate steps to control the flow of chemical from spillage source.  Call for assistance or raise the alarm if necessary.  Avoid direct contact with chemical or fumes.  Keep naked flames away from the area.  Limit the spill area by restricting its spread. e.g. with liquid use an absorbent material.  Dispose the spillage chemicals appropriately. 
  18. 18. Persons should be instructed to remove from the area and not enter fire area unless suitably protected.  A full face respirator with SCBA is considered the minimum protection for entry into the fire area.  If it cannot be quickly extinguished by the dry chemical extinguisher then appropriate fire control agent like foam should be used.  Water can be used to keep containers cool (unless the contents are incompatible with water).  Always keep the means of escape clear and every person must know about the route well. 
  19. 19. Remove affected clothing immediately.  Washing of contaminated skin with soap and water.  If chemical is splashed in the eye, wash it immediately in running water for 15 minutes.  Move person into fresh air and if breathing stops then provide mouth to mouth breathing.  Call doctor immediately. 
  20. 20. Goggles/face shield to protect eyes.  Chemical resistant gloves to protect hands.  Respirators with correct filter cartridges to prevent inhalation of pesticides in gas, mist or droplet form.  Rubber or PVC boots to protect feet.  Washable or chemical- resistant hat to protect head & scalp.  PVC apron for use during mixing. 
