How do you determine the safe distance of a barrier guard?
To determine the safe mounting distance for a barrier guard, first consider the largest opening in the guarding material. The current OSHA standard for safe distance as a function of opening size is set forth in Table O-10 of OSHA 29 CFR 1910.217 – Mechanical Power Presses.
How far away from the Saw do you hold the stock?
such that your fingers are at least 150 mm (6”) from the blade c. away from the saw, you don’t need to hold the stock in place d. as close as possible to the blade
How high above the stock should the saw blade be set?
To ensure safety set the saw blade 6mm (1/4”) above the stock when cutting. 17. Always use the proper blade designed for different operations…example a ripping blade for ripping material.
How to choose the right safety guard for your machine?
Guards and safety devices should be made of durable materials that will withstand normal use. They must be firmly secured to the machine where possible or secured elsewhere if attachment to the machine is not possible. Protect from falling objects: The safeguard should ensure that no objects can fall into moving parts.
How far should the safety guard be above the stock band saw?
1/8 to ¼ inchKeep guards in place at all times. The blade guard should be from 1/8 to ¼ inch above stock. Keep hands away from blade and do not open upper or lower bandsaw doors while blade is in motion. Maintain a balanced stance and keep your body under control at all times; do not overreach.
How far above the stock to be cut should you set the saw blade?
The Safest Cut With that in mind, the safest height to set a table saw blade is so it's just above the wood you are cutting. The general rule of thumb is that the blade should be set so it is 1/8” above the workpiece. If you make contact with the blade with your hand at this height, you're unlikely to lose a finger.
What is the number 1 safety rule of the band saw?
Never push on back of piece with fingers or thumb. Don't reach across the blade. Make all cuts under power, not while blade is coasting. Never remove guard unless authorized by Technician or WRL Manager.
What is the margin of safety for the band saw?
4”Maintain a 4” margin of safety! Your hands MUST be at least 4” away from the blade when the saw is running. 8. Plan ahead saw cuts to avoid backing out of curves whenever possible.
How high should the blade guides be set above your material bandsaw?
Adjust blade guard height to about 3 mm or 1/8 inch to 6mm or 1/4 inch above the top of the material being cut. Wider gaps will place tension on the blade and increase the risk of breaking. Ensure the blade is tracking correctly and runs freely in and against the upper and lower guide rollers.
How high should a table saw surface be?
When it comes right down to it, the proper height for your table saw depends on your height. While the average height tends to be 34 inches and the standard range is between 31 and 38 inches, the best choice for you will fall right about even with the distance of your thumb knuckle from the floor.
What is the minimum distance you should keep your fingers from the blade?
Allow the saw to reach full speed before starting the cut. Keep your fingers at least 2 inches from the side of the blade. Never put your fingers in front of the blade.
What is the closest you should put your fingers to the blade while it is running?
2. Do not put your fingers closer than two inches from the blade. 3. Do not place your hands directly in line with the blade while cutting stock.
Do band saws need guards?
Bandsaws must be guarded. Guarding must prevent access to the bandsaw blade but still allow the employee to see the material being cut. If practicable, employees should use a push stick to guide the work piece through the cutting process. A push stick allows employees to keep fingers and hands clear of the blade.
What are the safety rules of the saw?

What is the general rule for selecting a band saw blade for cutting curves?
This will keep the cuts nice and straight and you'll get a decent feed rate without breaking blades. On the other end of the scale, if you do contour sawing, use a blade that is narrow enough to cut the desired radius....Bandsaw Blade Width.Blade Width (Inches)Minimum Radius (Inches)1/45/83/81-1/21/22-1/25/844 more rows
How can location and distance keep employees safe?
Though not actual guards or devices, location and distance can keep employees safe by placing a machine in an infrequently traveled area or where it’s dangerous moving parts are not accessible. A thorough hazard analysis of each machine and situation is essential before using this safeguarding technique
Why are guards needed?
Guards designed and installed by the machine producer are desirable because they conform to the design and function of the machine, and they can be designed to strengthen the machine or to serve some additional functional purpose. User-built guards are sometimes necessary and have some advantages.
What are the hazards of rotating parts?
Rotating parts cause hazards such as in-running nip points. There are three main types of in-running nip points. Parts can rotate closely to each other in opposite directions while their axes are parallel to each other. When they run closely, the stock fed between two rolls produces a nip point.
Why is machine guard important?
Moving machine parts create workplace hazards and potential machinery-related injuries, making machine guards vitally important. All machines consist of three fundamental areas – the point of operation, the power transmission device and the operating controls. Machine safeguarding helps protect workers from preventable injuries in all three areas.
What are the different types of guards?
Guards are barriers which prevent access to dangerous areas. There are four general types of guards: 1 Fixed guards are permanent parts of a machine. These guards are preferable because they’re simple and permanent. 2 Interlocked guards automatically shut off or disengage power through a tripping mechanism when it is opened or removed. The machine cannot cycle or start until the guard is replaced. 3 Adjustable guards are useful because they accommodate various sizes of stock. 4 Self-adjusting guards allow the opening of these barriers to be determined by the movement of the stock. As the operator moves the stock into the danger area, the guard is pushed away, providing an opening that only is large enough for the stock.
Why is safeguarding important?
Proper safeguarding can enhance efficiency because it relieves a worker’s injury apprehensions.
How does an interlocked guard work?
Interlocked guards automatically shut off or disengage power through a tripping mechanism when it is opened or removed. The machine cannot cycle or start until the guard is replaced.
How far off the lower level is scaffolding required?
According to Subpart L of the Construction regulations (specifically 1926.451 (g) (1)), fall protection on scaffolding is not required until you are greater than 10’ off the lower level.
How many stories of wire should be tied off?
It is important to reiterate the ‘or two stories, whichever is less’ portion of the rule. Connectors may be required by law to be tied off at, say, 24’, if it was two stories of 12’ each. At the same time, they would not be required to be tied off if it was one story at 24’.
Why is fall protection not required?
OSHA states that fall protection is not required while the employees are in motion up to 24’ because they consider the multiple handholds and footholds of a vertical rebar assembly to provide similar protection as that of a ladder. Just as in the ladder standard, should that employee need to climb to a height greater than 24’, they would be required to utilize fall protection.
Why don't people think about fall protection?
Most people don’t think about fall protection when it comes to ladders and stairways, mostly because stairwells are often enclosed or have some type of railing already installed.
How many stories do you need to tie off a steel erection crew?
Connectors – those employees on a steel erection crew actively receiving and connecting steel members – do not need to be tied off up to 30’ or two stories, whichever is less.
How to build an extension ladder?
For extension ladders, there are three main considerations to keep in mind: 1 Have a 3’ extension of the ladder past the level to which you are climbing. 2 Have a 4:1 ratio of rise and run.#N#Basically, for every four feet high the ladder rises, place the base of the ladder one foot away from the structure. 3 Ensure you have three points of contact with the ladder at all times.#N#Two legs, one hand. Two hands, one leg. This means you will not be able to carry something, such as a bucket, up and down a ladder. This would force you to break the three-point rule. Find another means like pulling it up by a rope after transitioning or holding smaller items in a belt or pocket.
What is the key number for a ladder?
With ladders, the key number to remember is 24’ (1926.1053 (a) (18)). In any instance where the climb on a fixed ladder is greater than 24’ or where the climb is less than 24’ but the top of the ladder is greater than 24’ above a lower level, fall protection must be provided as one of the following: a ladder safety device or a self-retracting lifeline.
