(EHS) Environment Health Safety

  Theme of the Environmental day for this year is Solution to Plastic Pollution. 

  Guideline for Manual and mechanical material handling:- Manual materials handling  involves the handling, moving, lifting, and carrying of materials without the use of mechanical  equipment. Minimizing injuries that occur from materials handling requires planning about  these tasks. Following points must be taken into consideration while doing the manual and  mechanical material handling work. 1.  Ensure that the workers engaged for manual material handling operation must be trained for  manual material handling techniques and should be carried out under experienced  supervision. 2.  Ensure that the lifting, carrying or moving of material, articles or things does not endanger  the safety of nearby and other workers. 3.  Before lifting or shifting, size up the load first. If it is too big in size, ask for help of others. 4.  Take a round, inspect and look of work / nearest area before lifting and check whether it is  sli...

Type of Hazard Occupational Health Hazards can be classified into five catagories.  1. Chemical Hazard:- Dusts, fibres, gases, vapours, etc. and the associated hazards. 2. Physical Hazard:- Noise, vibration, radiation, heat, etc 3. Biological Hazard:- Bacteria, fungus, virus, human endoparasites, etc. 4. Psycho-social Hazard:- Stress, substance misuse, violence at work, etc. 5. Ergonomic Hazard:- Posture, workplace layout, etc.  

 Flash Back Arrester IS code- 11006 TERMINOLOGY 1. Flash Back arrestor:-  It is a device to stop or arrest or prevent the return of the flame which can result in an explosion or of the blow back of the oxygenated gas from damaging whatever it is intended to protect. These devices may incorporate two or more safety functions. 2. Safety Relief Device — It is a device intended to prevent rupture of the flame arrestor due to sudden built in pressure which can be in a form of safety valve, bursting disc or liquid seals connected to atmosphere. 3. Safety Seals — The flame arrestors or flash back arrestors are at times also referred as safety seals. 4. Flash Back — It is the return of the flame into an apparatus or line and its propagation against the flow of the gas. 5. Non-return Valve — It prevents the flow to return from the down stream side. 6. Flame Arrestors — Device which quenches a flame. MANUFACTURER’S TEST The following test should be carried o...

 1.  What is Fire? Fire is a rapid oxidation-reduction reaction that results in the production of heat and generally visible light. 2 Chemistry of Fire:  For a fire to start four elements are essential:   1. Fuel (combustible material and reducing agent).   2. Oxygen or oxidant or oxidiser (from the atmosphere).   3. Heat or source of ignition (necessary to start the fire initially, but maintained by the fire itself once it has started and   4. Maintenance of chain reaction through free radicals. 

  Objective: Monsoon is a major weather phenomenon and substantially impacts construction activities. This monsoon plan aims to identify the hazards and risks associated with monsoon at various stages of construction at the project site and to place adequate control measures to mitigate the risks and prevent accidents during the work, activities thereby facilitating the smooth progression of work. Potential Hazards during monsoon: Some of the potential hazards are Flooding and water accumulation at the site, immersion of materials, landslide, toppling of vehicles, electrocution, fall of man &material due to slippery nature of the site, lightning and thunderstorm attack, contamination of soil due to oil & fuel spill, accumulation of food and other waste, spreading of communicable diseases, mud spill on public roads while transporting the materials which may pose a hazard to motorists and pedestrians due to its slippery nature, local traffic congestion, accidents during trans...
