A wide variety of mechanical motions and actions may present hazards to the operator. These can include the movement of rotating members, reciprocating arms, moving belts, meshing gears, cutting teeth, and any parts that impact or shear .
What are the two major types of mechanical hazards?
- A crushing hazard through being trapped between a moving part of a machine and a fixed structure, such as a wall or any material in a machine;
- A shearing hazard which traps part of the body, typically a hand or fingers, between moving and fixed parts of the machine;
How many types of mechanical hazards are there?
In general, there are four main types : fixed, interlocked, adjustable, and self-adjusting.
What are the 4 types of machine guards?
- Fixed guards.
- Interlocking guards.
- Adjustable guards.
- Self-adjusting guards.
What is usually the most hazardous part of a machine?
- The point of operation. That point where work is performed on the material, such as cutting, shaping, boring, or forming of stock.
- Power transmission apparatus. ...
- Other moving parts.
Which comes under mechanical occupational hazard?
- Crushing.
- Shearing.
- Cutting or severing.
- Entanglement.
- Drawing-in or trapping.
- Impact.
- Stabbing or puncture.
- Friction or abrasion.
What is the cause and effect of mechanical hazard?
Mechanical hazards:
These include trauma, friction, pressure, vibration, pounding, abrasion and penetration injuries . Mechanical hazards cause irritant effects, or result in adaptive protective responses. The irritant effects are either acute or chronic.
What is the hazard of mechanical?
The main physical risks include noise, hand-arm and whole-body vibration, and heat stress. The main mechanical risks include cuts, lacerations, needle punctures, crushing, and contact with machines , as well as falls from heights, slips, trips and falls on the same level, and trench cave-ins.
What are mechanical safeguards?
Machine safeguards must meet these minimum general requirements: Prevent contact: The safeguard must prevent hands, arms or any other part of a worker’s body from contacting dangerous moving parts. Be secure : Workers should not be able to easily remove or tamper with the safeguard.
What is physical and mechanical hazard?
The first category of hazards is physical hazards, which is anything physical that may cause harm to the body. ... The second category of hazards is mechanical hazards, which are machines and other movable devices that may cause harm to the body .
What are the 2 types of primary safeguarding methods?
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?
Interlock guards
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 are nip points?
Woodworking » Nip Points
In-running nip points (or pinch points) are a special danger arising from rotating or reciprocating parts . They occur whenever machine parts move toward each other or when one part moves past a stationary object.
What is the best way to fix a hazard?
- Elimination – Sometimes hazards – equipment, substances or work practices – can be avoided entirely. ...
- Substitution – Sometimes a less hazardous thing, substance or work practice can be used.
Which of the following is an example of a non mechanical hazard?
1.2 Non-mechanical hazards
Non-mechanical hazards associated with machinery and equipment can include harmful emissions , contained fluids or gas under pressure, chemicals and chemical by-products, electricity and noise, all of which can cause serious injury if not adequately controlled.
What are two examples of appropriate guarding?
Examples of guarding methods are- barrier guards , two-hand tripping devices, electronic safety devices, etc.
