• Between the closing of the Civil War and the end of World War II,

– no single engineering tool surpassed the achievement of dynamite.

• Over the last 50 years,

– even more efficient and safer products known as water gels and emulsions and much more economical and less sensitive bulk delivery systems

• Coal mining accounts for two-thirds of consumed explosives of which more than 80% of it is ANFO.

• Today, computers are used to: drill, log and monitor blastholes

• automate blending and delivery with bulk trucks — determine bench heights and face conditions — analyze production efficiency, design blast patterns — and more.

Emulsion

Types of Blasting

• Sand blasting, which usually uses small grains of garnet as an abrasive to remove a coating or

polish a surface

Types of Blasting

• Glass bead blasting (eg glass) to remove build up of unwanted material on a surface without damaging the material underneath

Types of Blasting • Water blasting,

– where high pressure water gun is used to clean surfaces.

– These can range from small guns you can use at home to clean your car, or massive hoses used in industry to remove build up of scale inside massive tanks.

– Those hoses have

– enough pressure

– to cut through people

Hazard Vs. PPE

38

Hand Protection

39

Why is Hand Protection Important?

• It has been estimated that almost 20% of all disabling accidents on the job involve the hands

• Without your fingers or hands, your ability to work would be greatly reduced

Training

Employees required to use PPE must be trained to know at least the following

– When PPE is necessary

– What type of PPE is necessary

– How to properly put on, take off, adjust, and wear

– Limitations of the PPE

– Proper care, maintenance, useful life and disposal

– NB: Why do we use PPE
