What are the two types of primary safeguarding methods?

What are the two types of primary safeguarding methods?

Two primary methods are used to safeguard machines: guards and some types of safeguarding devices. Guards provide physical barriers that prevent access to danger areas.

How many types of machine guards are there?

Mechanical, electrical, hydraulic or pneumatic systems are used to actuate the guard. The mechanical interlocking of a power press, card machine and electrical (limit or microswitches) interlocking of headstock covers of many textile machineries are such examples.

What machine parts require guards?

The following are some examples of machines requiring point of operation guarding:

  • Guillotine cutters.
  • Shears.
  • Alligator shears.
  • Power presses.
  • Milling machines.
  • Power saws.
  • Jointers.
  • Portable power tools.

Which machine motion is the most dangerous?

Cutting action hazards involve rotating, reciprocating or transverse motion, where finger, head and arm injuries can occur and where flying chips and scrap material can strike a worker’s eyes or face. Cutting actions are dangers with bandsaws, circular saws, and boring or drilling machines.

What are electrical hazards?

An electrical hazard can be defined as. a dangerous condition where a worker could make electrical contact with energized equipment or a conductor, and from which the person may sustain an injury from shock; and/or, there is potential for the worker to receive an arc flash burn, thermal burn, or blast injury.

What are the three ways to prevent and control hazards?

Systems used to prevent and control hazards include:

  • ▪ Engineering Controls.
  • ▪ Administrative Controls.
  • ▪ Personal Protective Equipment (PPE)
  • ▪ Systems to Track Hazard Correction.
  • ▪ Preventive Maintenance Systems.
  • ▪ Emergency Preparation.

What are the types of pipelining hazards?

Pipeline Hazards

  • Structural Hazards. They arise from resource conflicts when the hardware cannot support all possible combinations of instructions in simultaneous overlapped execution.
  • Data Hazards.
  • Control Hazards.

What are the techniques used to remove control hazards?

Six Steps to Control Workplace Hazards

  1. Step 1: Design or re-organise to eliminate hazards.
  2. Step 2: Substitute the hazard with something safer.
  3. Step 3: Isolate the hazard from people.
  4. Step 4: Use engineering controls.
  5. Step 5: Use administrative controls.
  6. Step 6: Use Personal Protective Equipment (PPE)

How can we prevent physical hazards?

Examples of engineering controls for physical hazards include:

  1. Providing safety equipment to employees that reduces their exposure to the physical safety hazard.
  2. Reduce noises and vibrations present in the workplace.
  3. Place barriers between employees and physical hazards such as radiation or microwaves.

What is hazard prevention and control?

Effective controls protect workers from workplace hazards; help avoid injuries, illnesses, and incidents; minimize or eliminate safety and health risks; and help employers provide workers with safe and healthful working conditions.

What machine parts always require guards?

The shafting, flywheels, pulleys, belts, chain drives, etc. of power transmission apparatus less than 7 feet from the floor or working platform must be guarded.

What are 4 types of physical hazards?

Physical hazards include ergonomic hazards, radiation, heat and cold stress, vibration hazards, and noise hazards. Engineering controls are often used to mitigate physical hazards.

How can we prevent hazards?

Fortunately, there are only a few things to remember to prevent most of the problems and avoid potential hazards.

  1. Turn the power off.
  2. Inform others.
  3. Lockout/tagout (LOTO).
  4. Stay away from wires.
  5. Maintain equipment.
  6. Wear personal protective equipment (PPE).
  7. Avoid arc flash areas.

What are the 5 major categories of control measures?

NIOSH defines five rungs of the Hierarchy of Controls: elimination, substitution, engineering controls, administrative controls and personal protective equipment.

What are the three main types of control measures?

There are several types of control measures that fall into three main categories (in order of priority and effectiveness):…

  • Elimination.
  • Engineering.
  • Administrative.
  • Personal Protective Equipment.

What are the minimum requirements for protection and guards?

Guards must meet these minimum general requirements:

  • Prevent contact. The guard must prevent hands, arms, and any other part of a operator’s body from making contact with dangerous moving parts.
  • Secure.
  • Protect from falling objects.
  • Create no new hazards.
  • Create no interference.
  • Allow safe lubrication.

What are different types of guards?

There are four general types of guards:

  • Fixed.
  • Interlocked.
  • Adjustable.
  • Self-adjusting.
