Safety boots make use of steel or composite or alloy toe cap. But choosing the safety boot that suits your workplace plays a vital role. Safety boot should pass safety standard set by ANSI. For a Best Steel Toe Boots, it should pass the Impact Rating, Compression Rating and Metatarsal Rating test.
It is basically to test how much of a sudden jerk or weight, a toe cap able to withstand. In other words, it is to calculate that how much shock absorbent the cap is. When a heavy weight falls on the toe cap, it should not get bend or shattered. It should also absorb all the shock within itself and without passing it on to or crushing your feet.
Safety toe footwear tested to meet one of two units of measurement for impact rating. They are 50 or 75 pounds. Footwear rated I/50 will protect toes from an impact up to 50 pounds and I/75 will protect against 75 pounds.
As per ANSI standards a cap should have an Impact Rating of 1/50 or above. It means that, it should be able to absorb the shock when an object with a weight of 50 Pounds falls on it from a set height. So, do check the Impact Rating before making an order. The impact test performed by dropping a 50-pound weight at a height of 18 inches at a designated speed.
It is to test that how much compression the cap can withstand before getting bend or tearing part. Safety toe footwear tested to meet one of two units of measurement for compression rating: C/50 or C/75. Footwear with a C/50 rating can withstand compressive loads up to 1,750 pounds while C/75 footwear can withstand 2,500 pounds. But, ANSL got the minimum compression rating of 75 pounds and denoted as C/75. You should make sure that your safety boot is not less than 75.
Metatarsal protective footwear must first meet impact and compression rating of &% requirements. This type of test performed by dropping a 50-pound weight at a height of 18 inches on to the metatarsal guard.
