1 Trade Skills Sheet Metal Safety

2 2 Job safety Safety is based on knowledge, skill, and an attitude of care and concern. –Sheet metal workers must be fimiliar with the potential hazards of their craft and understand how to reduce or eliminate them. Example: sheet metal can have extremely sharp edges. In order to reduce the chance of receiving a serious cut, wear gloves for protection when handling sheet metal. In 1971, Congress created the Occupational safety and Health Administration (OSHA). –OSHA is responsible for setting and enforcing work safety standards.

3 3 In general, employers are required to provide a place of employment free of known hazards likely to cause death or injury. –Employers must comply with safety and health standards enacted by OSHA. –Employees are also required to comply with these standards.

4 4 Dressing with Safety in Mind Personal Protective Equipment (PPE) is clothing, hats, face shields, shoes, and other items that protect a persons body from danger. –PPE must meet OSHA standards.

5 5 Safety Boots Safety boots are worn to protect the feet. They generally have steel toes, reinforced or steel soles, and slip resistant soles. –Steel toes protect from falling or rolling objects –Reinforced or steel soles prevent penetration by sharp objects. –Slip resistant soles protect workers from wet, slippery, or other hazard surfaces. –NEVER wear canvas or sneakers on a job site.

6 6 Gloves Gloves are worn by sheet metal workers for several reasons. –They protect against metal splinters and rough edges. –Protruding screws or rivets. –Extreme temperatures on materials Work gloves are commonly made of: –Canvas, –Leather –Rubber Gloves are worn by sheet metal workers for several reasons. –They protect against metal splinters and rough edges. –Protruding screws or rivets. –Extreme temperatures on materials Work gloves are commonly made of: –Canvas, –Leather –Rubber

7 7 Safety glasses Safety glasses include traditional spectacles, goggles, and face masks. –In order for safety glasses to meet OSHA standards, glasses must not shatter or otherwise break during testing. –Safety glasses are classified as either: Basic impact glasses High impact glasses Safety glasses include traditional spectacles, goggles, and face masks. –In order for safety glasses to meet OSHA standards, glasses must not shatter or otherwise break during testing. –Safety glasses are classified as either: Basic impact glasses High impact glasses

8 8 Safety glasses should be worn whenever eyes are exposed to a hazard. –Much of the work done by sheet metal workers exposes the eyes to danger. Therefore, safety glasses are worn in the trade.

9 9 Hard hats All hard hats are designed to protect the head from falling objects. –Some also offer protection from electrical hazards Hard hats are worn whenever: –There is a danger of falling objects –Electrical conductors are exposed that might come n contact with the head. Sheet metal workers stand on scaffolding and ladders to hang duct work, so it can become a hazard to people working below them. Thus, hard hats are required.

10 10 Ladder safety There are three types of ladders: –Stepladders –Straight ladders –Extension ladders Ladders may be made of: –Wood –Metal –Fiberglass There are three types of ladders: –Stepladders –Straight ladders –Extension ladders Ladders may be made of: –Wood –Metal –Fiberglass

11 11 Because metal and water conduct electricity. NEVER use a metal or a metal reinforced ladder where direct contact with an electrical power source is possible.

Straight Ladder Step Ladder Extension Ladders

12 12 Ladders have to be UL approved before use on job sites. –Underwriters Laboratories (UL) is an independent, not-for-profit product safety certification organization. Before using ladders you should do some of the following: –Make sure it is in good working condition. –Don’t position a ladder where it can come in contact with electrical lines. –Don’t place a ladder in a doorway. If this is unavoidable, lock the door or have someone stand at the base of the ladder till the job is finished. –Extension ladders must overlap at least 3 feet between sections.

13 13 Ladder safety You should always face the ladder when climbing it. Don’t stand higher than the safe standing level noted on the ladder You should always face the ladder when climbing it. Don’t stand higher than the safe standing level noted on the ladder

14 14 Safety shoes on ladders prevent ladders from moving on slippery surfaces.

15 15 The safe way to lift an extension ladder or a straight ladder.

16 16 Scaffolding Safety When dealing with commercial and industrial construction, ladders may not simply be enough. It is sometimes necessary to construct a temporary platform to reach elevated work areas. These platforms are called scaffolding. When dealing with commercial and industrial construction, ladders may not simply be enough. It is sometimes necessary to construct a temporary platform to reach elevated work areas. These platforms are called scaffolding.

17 17 Material used to build scaffolding include metal for the frame and wood or metal for the platforms. –Using scaffolding near power lines must be carefully monitored. Because scaffolding is elevated and people will be standing on it, scaffolding must be securely supported and constructed.

18 18 Scissor lifts are often used in place of scaffolding. Sheet metal workers often use them indoors. –Basic Scaffolding safety rules also apply to scissor lifts.

19 19 When working on scaffolding follow some of these basic guidelines. –Follow all local, state and federal codes regarding scaffolding. –Install guardrails, toeboards, and screens on the platform. –Maintain the required distance from any power lines. –Don’t place makeshift ladders or other devices on the scaffolding to increase its height. –Use planking that is heavy enough to handle the load to be placed on it.

20 20 Welding Safety Welding is also used in sheet metal work to fasten sheet metal pieces together and can also be very dangerous. –The light from the arc is harmful to the eyes. –The light from the arc can also cause sunburn on exposed skin. –Melting metal can create toxic fumes –The high temperatures and sparks can create a fire.

21 21 When welding, follow some of these guidelines. –Cover all skin, including neck and forearms. –Never look at the arc with the naked eye. –Wear a helmet with proper shade to protect the eyes from the light and sparks. –Don’t weld metals containing cadmium, zinc, beryllium, or lead as they can release toxic fumes. If absolutely necessary to weld these metals, a respirator is required. –Keep a fire extinguisher handy When welding, follow some of these guidelines. –Cover all skin, including neck and forearms. –Never look at the arc with the naked eye. –Wear a helmet with proper shade to protect the eyes from the light and sparks. –Don’t weld metals containing cadmium, zinc, beryllium, or lead as they can release toxic fumes.

22 22 Soldering safety Soldering is used to join pieces of metal together or to prevent leakage in containers. Even though welding is more popular and more widely used, soldering continues to be a useful process in some applications. The tip of the soldering iron or copper can reach 500*F. –Handle the soldering iron carefully –Don’t handle the soldered material until is completely cooled.

23 23 Working with chemicals A variety of chemicals are used in sheet metal work to clean surfaces, remove rust, and to dissolve other substances. –These substances include: Solvents, Solutes Fluxes Solvents can be corrosive and can damage the skin on contact. Flux, used in soldering, can create harmful gases that must be properly ventilated.

24 24 When dealing with chemicals, keep in mind that they may be dangerous. –Store all chemicals properly and in proper containers. Keep them in a safe area and locked if necessary. –Wear face and eye protection from splashing substances –Know the location of the nearest eye washing station.
