Q: discus different type of fire and fire extinguishing method. A: fire is an exothermic chemical reaction between fuel and oxygen in the air which produces heat flame and light.         FIRE TRIANGLE Combustion or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species. The release of heat can produce light in the form of either glowing or a fla me. hence, the extinguishing methods would be. removing any one side of the triangle. ignition temperature -  cooling fuel - starvation oxygen - smothering chain reaction - chain breaking method Fires must be fought carefully depending on the materials involved. That is why they have been classified in 6 different categories: UK BASED CLASSIFICATION Class A  – Fires that involve solid or organic materials, such as wood, plastics, paper, textiles, or coal. Class B  – Fires that ...

assignment 2 Q 10. Explain in detail the role of trade unions in accident prevention in industries ans Objectives and Need of Trade Union Wages and salaries-Wages and salaries and the most important subjects of Trade Unions. In the organized industry, wages and benefits are determined through processes such as collective bargaining, wage boards, conciliation, and adjudication. Working of all these processes deserves systematic inquiry. Union power and objective facts hopefully influence the wage scene through these forums. Working conditions-Another major objective of the Trade Unions is to insure the safety of workers. While working every worker must be provided with basic facilities like. Drinking water, minimum working hours, paid holidays, social security, safety equipment, lights and others. Personnel policies-Any personal policy of the employer with respect to promotion, transfer and training may be chal...

assignment 2 Q 9: legal requirements under Factories Act, 1948 ans What are the provisions relating to health for employees working in factories and the manufacturing process addressed by the Factories Act, 1948? The main focus of Factories Act is towards the Health benefits to the workers. Health Chapter of the Act contains specification from Section 11 to 20. Detailed information of the sections of is provided as under: Section 11:  This section basically specifies the issues of cleanliness at the workplace. It is mentioned in the provision that every factory shall be kept clean and free from effluvia arising from any drain, privy or other nuisance. This includes that there should be no accumulation of dirt and refuse and should be removed daily and entire area should be kept clean. Section 12:  This section specifies on disposal of wastes and effluents. That every factory should make effective arrangements for the treatment of wastes and effluents due to the ...

assignment 2 6. Discuss the following: (a) Ventilation. (b) Illumination. ans Industrial Ventilation Solutions Ensure Healthy Air Quality Ventilation is an important part of any industrial HVAC system and helps ensure a safe and healthy working environment for all employees. Placing fans at strategic points inside a building may not be enough to provide adequate ventilation for the workforce, especially if we oversee a factory or warehouse facility, or are around chemicals and other contaminants. Government safety agencies suggest a better solution is using motorized building ventilation systems because they are designed to remove air and contaminants, reducing harmful elements to a safe level. Indoor Air Quality Indoor air quality is important to workers’ health. The Occupational Safety and Health Administration links poor air quality to symptoms that can include everything from headaches and fatigue to eye, nose, throat and even lung irritation. Asthma is one h...

assignment 2 Q 7. Discuss in detail about the Human factors contributing to accidents ans Human factors Human factors are responsible for large number of accidents that occur in a workplace. The following human factors are common causes of accidents: Memory lapses (including forgetting a step in the work process or a safety measure) Impaired judgment or reduced reasoning power Inattention or distraction Delayed or false sensation of the sensory organs Lack of competence and experience Skill level inadequate for the task performed Personality or attitude, such as negligence, arrogance, or overconfidence Poor risk perception due to poor knowledge and experience The Interaction Of Human Factors Let’s examine the interaction of three human factors: people, workplaces and management. Any reasonable number of the elements listed under each individual human factor has the potential to contribute to workplace accidents, creati...

assignment 2 Q 2. Describe in detail about the principles and various types machine guarding. ans Fixed Guards As its name implies, a fixed guard is a permanent part of the machine. It is not dependent upon moving parts to perform its intended function. It may be constructed of sheet metal, screen, wire cloth, bars, plastic or any other material that is substantial enough to withstand whatever impact it may receive and to endure prolonged use. This guard is usually preferable to all other types because of its relative simplicity and permanence. Interlocked Guards When the interlocked guard is opened or removed, the tripping mechanism and/or power automatically shuts off or disengages, and the machine cannot cycle or be started until the guard is back in place. An interlocked guard may use electrical, mechanical, hydraulic or pneumatic power or any combination of these. Interlocks should not prevent “inching” by remote control, if required. Replacing the guard sho...

Machine guarding Where Mechanical Hazards Occur Dangerous moving parts in these three basic areas need safeguarding: 1. The Point of Operation- The point of operation is that point where work is performed on the material, such as cutting, shaping, boring or forming of stock. 2.  Power Transmission Apparatus- Power transmission apparatus are all components of the mechanical system that transmit energy to the part of the machine performing the work. These components include flywheels, pulleys, belts, connecting rods, couplings, cams, spindles, chains, cranks and gears. 3.  Other Moving Parts- Other moving parts include all parts of the machine that move while the machine is working. These can be reciprocating, rotating and transverse moving parts, as well as feed mechanisms and auxiliary parts of the machine. Hazardous Mechanical Motions and Actions - Rotating Motion, Reciprocating Motion, Transverse Motion, Cutting Action, Punching Action, Shearing Action, Be...

assignment 2 Q 1. Describe the checklists to be followed in working at high scaffolds and ladders. ans Ladders 1. Application  ● Conduct risk assessment at the workplace where a ladder will be used to identify the potential hazards. (e.g. Is there a danger of electric shock?  Is the ladder placed on a busy passageway?)  ● Identify the type and nature of work.  ● Consider the frequency and duration of using the ladder.  ● Be certain about the application of the ladder to be used.  ● Consider using other access equipment that is safer than the ladder. 2.  Selection  ● Use the ladder in accordance with the manufacturer's instruction is of paramount importance.  ● Use the right type of ladder and ensure it is structurally sound.  You may need to use a straight ladder, a stepladder or other access equipment (such as a mobile ladder scaffold).  ● Choose the ladder that is suitable for the job - do not u...

Q 9. Explain process safety management concepts and how safety of process plants is integrated to its design, construction, maintenance and operation ans The Occupational Safety and Health Administration (OSHA) created the first PSM requirements in 1992 in response to a series of catastrophic incidents related to highly hazardous chemicals (HHC). These requirements have been updated and expanded several times in the last two decades, and all HHC-related companies should keep a lookout as they operate and expand. To make sure your company is compliant, keep in mind the following 14 elements that OSHA inspectors will look for when they review your PSM program. 1. EMPLOYEE PARTICIPATION Perhaps one of the most important mandates, the employee participation clause requires that employees—including production and maintenance staff—be involved in every aspect of the PSM programs at their respective worksites. They must also be represented at the meetings where PSM-related is...
