Safety for Assembly 211
The class Safety for Assembly provides a comprehensive overview of different safety precautions for assembly. Assemblers must wear proper clothing and protective equipment, which varies for different tasks. A safe assembly site is organized and clean, with clear paths around workstations. Working in assembly requires an awareness of electrical, forklift, and point of operation safety precautions, as well as proper fall prevention and tool handling procedures. Applying ergonomics to assembly helps prevent injury caused by repetition, poor posture, and excessive force.
Before beginning any assembly work, assemblers must know the appropriate safety precautions and be trained to use required protective equipment. This can be challenging because there are different precautions for different tasks. After taking this class, users will be familiar with the basic safety guidelines for assembly, which will prepare them to perform various assembly operations safely and effectively.

A larger part or product that consists of several other components that have been joined together. Assemblies are made up of multiple smaller subassemblies.
The process of joining components together into a larger or completed part. Assembly methods include mechanical fastening, adhesive bonding, and welding.
The place where assembly is performed. Employees at an assembly site require PPE for safety.
A device used to support the spine by limiting its motion. A back brace is a type of PPE for lifting.
Safety equipment that prevents assembler's hands from entering the point of operation. Barrier guards should never be tampered with.
A material or object that is being joined by assembly. The place where a fastener attaches to the base component is called the point of operation.
A power-driven tool that uses compressed air to clear away industrial debris from parts, workstations, and machines. Blow guns should not be connected unless they will be used immediately.
A safety device composed of straps connected around the legs, waist, and shoulders that is attached to a hoist. A body harness may be required when working at elevated heights to prevent falls.
Resistant to being drawn, stretched, or formed. Brittle materials are more likely to chip, shatter, or cause fasteners to ricochet.
The maximum amount of power that a tool can operate at safely. Capacity is outlined in a power tool's specifications.
To squeeze together. Muscles contract when used to perform a task.
Ear wear that covers the entire outer ear to protect hearing. Earmuffs protect the entire ear from debris or sparks as well.
Ear wear that is inserted into the ear to protect hearing. Earplugs protect the inner ear from noise.
The flow of electricity through the body. Electric shock can cause falls, burns, and even death.
A tool that is powered by an electrical current. Electric tools pose the risk of electric shock and other injuries.
The scientific study of equipment, workspace, and production environment design to increase comfort, safety, and productivity. Ergonomic concerns include force, posture, and repetition.
A protective device that guards the face and eyes. Face shields can be required PPE for some assembly operations.
A device that holds two or more objects together or locates them in relation to each other. Common fasteners include screws, bolts, rivets, and nails.
A tool used for assembling a fastener into a base component. Fastening tools include hand and power tools such as screwdrivers, wrenches, rivet guns, and more.
A flame-resistant, tarp-like device that is used to isolate a work area. Fire shields protect bystanders from UV radiation, flying debris, and sparks.
Easily ignited and capable of starting a fire. Flammable materials should be kept away from electric tools.
A push or pull that gives energy to an object. Assemblers exerting excess force is an ergonomic concern.
A powered industrial vehicle with a pronged platform on the front for lifting material. Forklifts are used to lift and transport heavy loads.
Safely connected to a neutral body, like the earth, that can absorb stray electrical charges. Electric tools must be grounded to help prevent electric shock.
A tool powered by an operator's manual force. Hand tools must be in good working condition to avoid injury.
A power-driven tool that uses a discontinuous drive clutch and compressed air to achieve torque. Impact wrenches should never be connected unless they will be used immediately.
A component of a wrench that grips bolts and nuts. Jaws that are dull can cause a wrench to slip, creating a safety hazard.
A field of light that stops a machine when the light is blocked by an object. Light curtains should be checked to ensure they are operating properly before assembly begins.
A method of protecting employees from accidental machine startup by locking and labeling devices. Lockout/tagout renders a tool or machine inoperable.
The joining of two or more materials with devices called fasteners. Mechanical fastening is often used for parts that require disassembly and reassembly.
Occupational Safety and Health Administration
OSHA. A government agency that sets the standards for working conditions in the United States. The Occupational Safety and Health Administration creates regulations that ensure that assemblers work in safe and healthy environments.

personal protective equipment
PPE. Any clothing or device worn to minimize exposure to hazards and prevent injury. Personal protective equipment may include eye and ear protection, safety footwear, gloves, and other devices.
Any place where two components meet. Pinch points can trap body parts and cause serious injury.
A permanent open-sided structure that is elevated above the surrounding floor or ground. A platform allows assemblers to work at elevated heights.
A tool that is powered by compressed air. Pneumatic tools should not be connected or loaded unless they will be used immediately.
point of operation
The area where work is performed, often where the tool comes into contact with the workpiece. In fastening, the point of operation is the place where the fastener contacts the base component.
How a person stands, sits, or arranges his or her body. Good posture can reduce the occurrence of ergonomic injuries.
A tool powered by an external source of energy such as electricity or compressed air. Power tools require more safety precautions in addition to those for hand tools.
Personal protective equipment. Any clothing or device worn to minimize exposure to hazards and prevent injury. PPE may include eye and ear protection, safety footwear, gloves, and other devices.

A part that consists of smaller parts or sub-components and is used in the assembly of larger parts. Subassemblies are joined with other components to create larger assemblies.
Safety equipment that consists of ropes that are suspended from the ceiling and attached to the assembler. Suspension ropes may be required when working at elevated heights to prevent falls.
The amount of rotational force required to tighten a fastener. Reaching torque with a fastening tool can cause a jerk in an assembler's arm called torque reaction.
A jerk that assemblers feel in the handle of the tool they are using when torque is reached. Torque reaction is undesirable and is an ergonomic concern because it can cause injury.
UV. Potentially harmful light that is invisible to the naked eye because it consists of wavelengths shorter than those of visible violet light. Ultraviolet light produces radiation that can burn the skin and the eyes.
