The document discusses the 1984 Bhopal disaster in India, one of the worst industrial disasters in history. It provides background on Union Carbide India Limited (UCIL), which operated the pesticide plant in Bhopal. In the early hours of December 3, 1984, around 45 tons of toxic methyl isocyanate gas leaked from the UCIL plant, exposing hundreds of thousands of people. At least 3,800 people died and many more suffered severe injuries or long-term health issues from the leak. The document examines the causes and timeline of the incident as well as UCIL's failed emergency response.
The document discusses safety in construction. It aims to provide a safe workplace free of recognized hazards. A key goal is to prevent workplace accidents and personal injuries between moving equipment and workers on foot. Common causes of injuries are being struck by or caught between equipment. The document outlines various hazards like electrical, vehicles/equipment, excavation, and failures of centering/shuttering/shoring. It recommends management commitment to safety, pre-construction hazard analysis, equipment maintenance, training, and periodic review of procedures to improve safety when personnel and mobile equipment operate in close proximity.
The document summarizes the legislative history and key provisions of Indian factory acts from 1911 to 1934. The 1911 act introduced health and safety provisions and set maximum hours of 12 per day for adults and 6 for children. The 1934 act further reduced maximum hours, required medical certificates for workers, prohibited night work for women and children, and mandated overtime pay and welfare facilities. It defined what constitutes a factory and gave powers to inspectors. Later amendments in 1922 reduced employee thresholds for a factory to be covered and prohibited child labor under age 12.
This document provides a history of labor legislation in India from the 19th century to 1976. It notes that early industrialization led to poor working conditions, which sparked labor unrest and activism beginning in the late 1800s. This led the British government to establish commissions and pass the first Factory Act in 1881, though it proved inadequate. Continued agitation resulted in new Factory Acts in 1891, 1911, 1922, and 1934 that gradually imposed restrictions on child labor, women's work hours and conditions, maximum work hours, holidays, and safety standards. The acts aimed to balance workers' rights with national economic interests. The document outlines key amendments each act introduced to improve labor protections over time in India.
The document discusses the Factories Act of 1948 and its amendments related to occupational health and safety in India. It provides an overview of the key government bodies responsible for enforcement of the Act. It also summarizes some of the major provisions of the Act regarding safety, health, welfare, hazardous processes, dangerous operations, and responsibilities of occupiers.
The document provides an overview of the Factories Act of 1948 and its legislative history in India. Some key points:
- The Factories Act of 1948 consolidated previous factory acts and aimed to improve working conditions for laborers. It extended to the entire country and came into force in 1949.
- Previous factory acts dated back to 1881, gradually expanding protections for certain groups and imposing limits on work hours. The 1948 act aimed to standardize regulations across industries.
- The act defines terms like "factory," "occupier," and "manufacturing process." It covers health, safety, hazardous processes, licensing, authorities, and administrative provisions.
- Key authorities under the act include the Chief Inspector of Fact
The document summarizes the major amendments made to the Factories Act in India over time, beginning in 1911. Key changes included restrictions on working hours, especially for women and children, requirements for facilities like drinking water and toilets, and increased penalties for violations. Major amendments were made in 1922, 1934, and 1987 after industrial disasters, with the 1987 changes adding new provisions for hazardous processes and increasing oversight and responsibilities of occupiers.
This document discusses various terms and techniques related to safety management, including:
1. Safety tours, surveys, sampling, inspections, and audits which are used to monitor workplace safety standards.
2. The relationship between absenteeism and safety, and how safety contacts can help address issues caused by carelessness or ignorance.
3. The importance of promoting both on-the-job and off-the-job safety, as well as tools like job safety analysis (JSA) that are used to control accidents and losses.

Falls are the leading cause of deaths in the
construction industry.
Most fatalities occur when employees fall from open-
sided floors and through floor openings.
Falls from as little as 4 to 6 feet can cause serious
lost-time accidents and sometimes death.
Open-sided floors and platforms 6 feet or more in
height must be guarded.

What Is A Scaffold?
An elevated, temporary work
platform
Three basic types:
Supported scaffolds -- platforms
supported by rigid, load bearing
members, such as poles, legs,
frames, & outriggers
Suspended scaffolds --
platforms suspended by ropes or
other non-rigid, overhead support
Aerial Lifts -- such as “cherry
pickers” or “boom trucks”

SCAFFOLDS HAZARDS
• Falls from elevation – caused
by slipping, unsafe access, and
the lack of fall protection
• Struck by falling tools / debris
• Electrocution – from overhead
power lines
• Scaffold collapse - caused by
instability or overloading
• Bad planking giving way

recognize its hazards and
the correct procedures to
use
Falls and Equipment
To protect employees from these hazards, OSHA requires the employer to take the following precautions:
• Keep materials or equipment that might fall or roll into an excavation at least 2 feet from the edge of excavations, or have retaining devices, or both.
• Provide warning systems such as mobile equipment, barricades, hand or mechanical signals, or stop logs, to alert operators of the edge of an excavation. If possible, keep the grade away from the excavation.
• Provide scaling to remove loose rock or soil or install protective barricades and other equivalent protection to protect employees against falling rock, soil, or materials.
• Prohibit employees from working on faces of sloped or benched excavations at levels above other employees unless employees at lower levels are adequately protected from the hazard of falling, rolling, or sliding material or equipment.
• Prohibit employees under loads that are handled by lifting or digging equipment. To avoid being struck by any spillage or falling materials, require employees to stand away from vehicles being loaded or unloaded. If cabs of vehicles provide adequate protection from falling loads during loading and unloading operations, the operators may remain in them.
Reference 1926.650
Shield (shield system) -- a structure able to withstand a cave-in and protect employees with the structure. Shields can be permanent structure or can be designed to be portable and moved along as work progresses. Also known as trench box or trench shield.
Shoring (shoring system) -- a structure such as a metal hydraulic, mechanical or timber shoring system that supports the sides of an excavation and which is designed to prevent cave-ins.
Sloping (sloping system) -- protects employees from cave-ins by excavating to form sides of an excavation that are inclined away from the excavation to prevent cave-ins. The angle of incline varies with differences in such factors as the soil type, environmental conditions of exposure, and application of surcharge loads.

Reference 1926.652(a)
Protective system – a method of protecting employees from cave-ins, from material that could fall or roll from an excavation face or into an excavation, or from the collapse of adjacent structures. Protective systems include support systems, sloping and benching systems, shield systems, and other systems that provide the necessary protection.
Several factors come into play when developing a total “protective system”. The design of of the system itself, how materials and equipment are handled in and around the excavation, and installation and removal of protective system components.

Reference 1926.652, 1926.652(b), 1926.652(c)
Benching -- excavating the sides of an excavation to form one or a series of horizontal levels or steps, usually with vertical or near-vertical surfaces between levels.
Shoring or shielding is used when the location or depth of the cut makes sloping back to the maximum allowable slope impractical. There are two basic types of shoring, timber and aluminum hydraulic.
Trench boxes (shielding) are different from shoring because instead of supporting the trench face, they are mostly serve to protect workers from cave-ins. The excavated area between the outside of the trench box and the face of the trench should be as small as possible. The space between the trench box and the excavation side may be backfilled (or other means may be used) to prevent lateral movement of the box. Shields may not be subjected to loads exceeding those which the system was designed to withstand. Trench boxes may be used in combination with sloping and benching.

Instructor note: OSHA Standard Exemptions:
House foundation/basement excavations (including those that become trenches by definition when formwork, foundations, or walls are constructed) are exempt from the OSHA standard. The specific information regarding the interpretation of this exemption may be found on the OSHA public web site. Reference 29 CFR 1926.652.
The exemption specifies height and width for the excavation, impact of water and environmental conditions, soil and equipment factors, and operation of heavy equipment in the vicinity.
Reference 1926.652(a) and 1926.652(c)(1)
Designs for aluminum hydraulic shoring shall be in accordance with paragraph (c)(2), but if manufacturer's tabulated data cannot be utilized, designs shall be in accordance with appendix D.
Employees exposed to potential cave-ins must be protected by sloping or benching the sides of the excavation, by supporting the sides of the excavation, or by placing a shield between the side of the excavation and the work area.
1926 Subpart P Appendix D Aluminum Hydraulic Shoring for Trenches
Contains information that can be used when aluminum hydraulic shoring is provided as a method of protection against cave-ins in trenches that are not more than 20 feet deep.

The employer or his designee must select and construct designs of support systems, shield systems, and other protective systems
Trenches more than 5 feet require shoring or must have a stabilized slope
Trenches less than 5 feet - a competent person must inspect to determine that a protection system is not necessary in soils where there is no indication of a potential cave-in
In hazardous soil conditions trenches under 5 feet need protection
Reference 1926.651(k)
Daily inspections of excavations, the adjacent areas, and protective systems shall be made by a competent person for evidence of a situation that could result in possible cave-ins, indications of failure of protective systems, hazardous atmospheres, or other hazardous conditions. An inspection shall be conducted by the competent person prior to the start of work and as needed throughout the shift. Inspections shall also be made after every rainstorm or other hazard increasing occurrence. These inspections are only required when employee exposure can be reasonably anticipated.
Reference 1926.651(k)
(2) Where the competent person finds evidence of a situation that could result in a possible cave-in, indications of failure of protective systems, hazardous atmospheres, or other hazardous conditions, exposed employees shall be removed from the hazardous area until the necessary precautions have been taken to ensure their safety.
Reference 1926.652(a)
Each employee in an excavation shall be protected from cave-ins by an adequate protective system except when:
Excavations are made entirely in stable rock; or
Excavations are less than 5 feet in depth and examination of the ground by a competent person provides no indication of a potential cave-in.
Protective systems shall have the capacity to resist without failure all loads that are intended or could reasonably be expected to be applied or transmitted to the system.

The issues of how to provide fall protection for employees at construction sites are difficult ones. There are so many different types of work and so many different kinds of fall hazards that it is not possible to organize fall protection into a neat set of rules that fit all situations. OSHA reflects this difficulty when it places its rules for fall protection in several different subparts in the Construction Standards, depending primarily on the nature of the work being undertaken. There are separate locations, for example, for fall protection during work on scaffolds, during work on certain cranes and derricks, during work in tunnels, during work on stairways and ladders, during steel erection, etc.

Reference 1926.501(b)(1)
General rule: If an employee can fall six feet or more onto a lower level, fall protection must be provided.
What type of fall protection will I need?
In most cases, a guardrail system, a safety net system, or a personal fall arrest system must be used. In some cases fences, barricades, covers, equipment guards or a controlled access zone may be used.
Employees must be protected not just from falling off a surface, but from falling through holes and from having objects fall on them from above.

Reference 1926 Subpart M App C
An employer may use a variety of fall protection systems to protect employees. These systems must meet OSHA requirements. The competent person must make frequent and regular inspections, as required, to determine if these systems meet OSHA requirements before employees rely on these systems. More detail may be found in 29 CFR 1926.502.
Employers engaged in leading edge work, precast concrete erection work, or residential construction work who can demonstrate that it is infeasible or it creates a greater hazard to use conventional fall protection equipment may develop a fall protection plan that provides other measures to be taken to reduce or eliminate fall hazards for workers. Fall protection plans must conform to OSHA provisions and be prepared by a qualified person. Although a fall protection is required, it does not have to written, nor does it have to be site specific. Fall protection plans must identify locations where conventional fall protection methods cannot be used and set up controlled access zones and any necessary safety monitoring systems.
See STD 3-0.1A
Reference 1926.502(b) and 1926.502(j)
How do guardrail systems protect me from falling?
Guardrail systems provide a barrier to protect the employee from falling:
Top edge of the guardrail must be 39-45 inches above the walking/working level.
There must also be protection from falling between the top rail and the walking/working surface. Midrails, screens, mesh, or intermediate vertical members may be used for this protection. There are specific requirements for their installation.
The protective barriers must be strong enough to support a falling employee. Wood, chain and wire rope may be used for top rails and midrails.
Reference 1926.502(c)
How do safety net systems protect me?
Safety net systems catch the employee if he/she does fall. The safety nets:
Must be strong enough to support a falling employee;
Must have sufficiently small mesh openings so the employee cannot fall through the net;
Must be close enough to the surface of the walking/working surface so that the fall into the safety net will not still injure the employee (never more than 30 feet below the walking/working level);
Must be close enough to the edge of the working surface (the outer edge of the net between 8-13 feet from the edge of the walking/working surface, depending on the distance to the walking/working surface) so that the falling employee will not slip past the net.
Where should I expect fall protection to be provided?
When an employee is on a walking/working surface that has an unprotected edge.
When an employee is constructing a leading edge.
When an employee may fall through a hole in the walking/working surface.
When an employee is working on the face of formwork or reinforcing steel.
When employees are on ramps, runways and other walkways.
When employees are working at the edge of an excavation, well, pit, or shaft.
When employees are working above dangerous equipment (even employees working less than six feet over dangerous equipment must be protected).
When an employee is performing overhand bricklaying and related work.
When an employee is performing roofing work.
When an employee is engaging in precast concrete erection (with certain exceptions).
When an employee is engaged in residential construction (with certain exceptions).
Reference 1926.501(b)(6)
Ramps, runways, and other walkways must be protected by guardrail systems when employees can fall 6 feet or more.
The walking/working surface must be strong enough to support employees safely. If not, employees may not work on the surface. This knowledge will be gained during frequent and regular inspections made, as required, by competent persons designated by the employer.

Duty to have fall protection.
OSHA requires employees to provide fall protections systems that must meet certain criteria:
Walking and working surfaces must have sufficient strength and structural integrity to support employees safely.
Employers must provide protection to employees working in areas with unprotected sides or edges 6 feet or more above a lower level.
Specific types of protection are required in work areas with leading edges, in hoist areas, in work areas with holes, ramps, runways, and other walkways, in areas where excavations are being conducted, where dangerous equipment is being used, during overhand bricklaying, in roofing, in precast concrete erection, in residential construction, and in work areas with wall openings.
Hard hats are required when workers may be exposed to falling objects.
Other requirements include either
use of toeboards, screens or guardrail systems; or
use of a canopy structure; or
barricading area to which objects could fall and prohibiting employees from entrance.
1926 Subpart L - Scaffolding
This presentation is designed to assist trainers conducting OSHA 10-hour Construction Industry outreach training for workers. Since workers are the target audience, this presentation emphasizes hazard identification, avoidance, and control – not standards. No attempt has been made to treat the topic exhaustively. It is essential that trainers tailor their presentations to the needs and understanding of their audience.
This presentation is not a substitute for any of the provisions of the Occupational Safety and Health Act of 1970 or for any standards issued by the U.S. Department of Labor. Mention of trade names, commercial products, or organizations does not imply endorsement by the U.S. Department of Labor.
This standard applies to all construction employees and employers who work on, under, or in close proximity to scaffolding and aerial lifts. Employees erecting and dismantling scaffolds also are covered.

Aerial lifts – Vehicle-mounted devices used to get a worker to an elevated position, — referred to as “cherry pickers” or “boom trucks”
About 2 of every three construction workers (2.3 million) work on scaffolds frequently.
Protecting these workers from scaffold-related accidents would prevent 4,500 injuries and 50 deaths every year, at a savings of $90 million in workdays not lost.
See the Scaffolding Technical Links page - www.osha.gov/SLTC/scaffolding/index.html
Cinder blocks or other similar materials should not be used to support a scaffold because they could be crushed.
Any time there is inadequate support, improper construction or a shift in the components of the scaffold (including the base upon which the structure is built), there is danger of collapse.
