Basic Safety Flashcards

Benching systems cannot be used in _____.

Answer: Type C soils

Benching systems cannot be used in Type C soils because these soils are cohesive, granular, and have a very low unconfined compressive strength, making them highly unstable. Benching requires stable soil conditions to create safe, stepped excavations. For Type C soils, shoring or sloping at a much flatter angle is typically required to prevent trench collapse and ensure worker safety.

Safety _________.

Answer: is a learned behavior and attitude

Safety is fundamentally a learned behavior and attitude, not something that comes naturally. It requires training, awareness, adherence to procedures, and a proactive mindset from all individuals in a workplace. Developing a strong safety culture involves continuous education and reinforcement of safe practices to prevent accidents.

The activity that consists of breaking a job into its component tasks and then analyzing each step for potential hazards is called a _____.

Answer: job safety analysis

The activity that consists of breaking a job into its component tasks and then analyzing each step for potential hazards is called a job safety analysis (JSA). A JSA identifies hazards, assesses risks, and determines the safest way to perform each task. This systematic approach helps prevent accidents and injuries by proactively addressing potential dangers before work begins.

Which of the following is life-threatening?

Answer: Heat stroke

Heat stroke is a life-threatening medical emergency caused by prolonged exposure to high temperatures, resulting in the body's inability to regulate its temperature. Unlike heat cramps or heavy sweating, which are less severe heat-related illnesses, heat stroke can lead to organ damage, brain damage, or death if not treated immediately. It requires urgent medical attention.

Charred sections of a welding hose close to the torch may be caused by _____.

Answer: flashback

Charred sections of a welding hose close to the torch are often caused by a flashback. A flashback occurs when the flame burns back into the torch, hose, or even the regulator, which can be extremely dangerous and cause damage or explosions. Flashback arrestors are safety devices designed to prevent this from happening and protect the welder.

A person who is capable of identifying existing and predictable hazards and has authorization to take prompt corrective measures to eliminate such hazards is a _____ person.

Answer: competent

A 'competent person' is defined by OSHA as someone capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them. This designation is crucial in construction and other industries for ensuring on-site safety and compliance.

When stepping off a ladder onto a platform or roof, the top of the ladder should extend above the point where the ladder touches the platform or roof by at least _____.

Answer: 3 feet

When stepping off a ladder onto a platform or roof, the top of the ladder should extend at least 3 feet above the landing surface. This extension provides a secure handhold for workers as they transition on and off the ladder, significantly improving stability and preventing falls. It is a critical safety requirement for ladder use to ensure safe access and egress.

The D-ring or support point on a safety harness should be placed _____.

Answer: between your shoulder blades

The D-ring or support point on a safety harness should be placed between your shoulder blades. This positioning ensures that if a fall occurs, the force is distributed safely across the body, minimizing injury and keeping the worker upright. Incorrect D-ring placement can lead to severe injuries or make rescue difficult, compromising the effectiveness of the fall arrest system.

When everyone in the company understands the value of a safe work environment, _____.

Answer: a safety culture is created

When everyone in the company understands and values a safe work environment, a strong safety culture is created. A safety culture is an organizational atmosphere where safety is a top priority, integrated into all aspects of work, and shared by all employees. This leads to fewer accidents, increased productivity, and improved morale, benefiting the entire organization.

Employers are required to report fatalities and catastrophes to OSHA within _____ hours.

Answer: 8

Employers are required by OSHA to report all fatalities and catastrophes (hospitalizations of three or more employees) to OSHA within 8 hours. This prompt reporting allows OSHA to investigate serious incidents quickly, identify hazards, and prevent similar occurrences in the future. Failure to report within this timeframe can result in penalties and hinder safety improvements.

A system that protects workers from hazardous energy while they work with machines and equipment is referred to as _____.

Answer: lockout/tagout

Lockout/tagout (LOTO) is a safety procedure used to ensure that dangerous machines are properly shut off and not able to be started up again prior to the completion of maintenance or servicing work. It protects workers from hazardous energy by physically locking and tagging energy-isolating devices, preventing accidental energization or release of stored energy. This system is critical for preventing serious injuries or fatalities during machine servicing.
