Confined Space Entry or Work

Confined Space Entry or Work

What is a confined space?

  • Not large enough to enter.

  • Restricted means for entry and exit.

  • Not designed for continuous employee occupancy.

  • Confined space work may require a permit and competent foreman on site.

Crane & Derrick Safety

Crane & Derrick Safety

What is a crane? What is a derrick?

  • Cranes come in many forms and sizes, a derrick is a type of crane.

What hazards are encountered when cranes are on a job site?

  • Electrocution from overhead power lines

  • Falling objects

  • Overloading crane capacities (causing tip over or structural damage to the crane)


Examples of cranes:

Tower Crane

Telescopic Mobile Crane

Derrick Crane

Truck Mounted Picker Crane

Mobile Crane

Elevated Work Platform & Aerial Device

Elevated Work Platform & Aerial Device

What is an elevated work platform?

  • Any device that is designed to allow employees to work from a raised height.


What is an aerial device?

  • Aerial devices are vehicle mounted devices that extend or articulate workers into position to perform work.

Examples: aerial ladder, boom, orchard man-picker, cherry pickers, scissor lift

EPA Compliance

EPA Compliance

  • EPA stands for Environmental Protection Agency (EPA)

  • The EPA is the government agency that is responsible for protecting the environment.

  • Compliance with the EPA generally is an issue when there is a presence of:

    • harmful hazards in the air​

    • air quality management protocols

    • potential exposure to asbestos or lead

    • land waste

    • water contamination

    • chemicals and/or toxins present at the job site

Excavation & Trenching

Excavation & Trenching


Excavation​'s are defined to include trenches. Excavations are any man-made cut, cavity, trench, or depression in the earth's ground surface. Excavations are created for anything from small underground cellars to highways.


Trenches (trench excavation) are a narrow excavation made below the surface of the ground. In general, the depth is greater than the width, but the width of a trench (measured at the bottom) is not greater than 15 feet.

NOTE: Always take note of the measurements of a trench because different depth and length may require additional safety measures and/or OSHA requirements.


Injuries are very often associated with excavation. Some hazards to be aware of while excavating are cave-ins, the striking of underground utilities, falling tools, material, and equipment, and hazardous air contaminants or oxygen-deficient environments.

Fall Protection

Fall Protection

What is fall protection?​

  • The simplest answer is, if any employees are working at more than four feet (4') above a lower level and do not have some type of fall protection, you MAY be in violation.

Examples of Fall Hazards:

  • elevated work platforms

  • aerial devices

  • elevated surfaces

  • roofs

  • uneven catwalks and walkways

  • working with ladders, stair, scaffolds

  • open trenches and excavation

  • slippery, cluttered, or unstable walking or working surfaces

  • floor holes

Hazard Communicatin & SDS

Hazard Communication & Safety Data Sheets (SDS)

A Hazard Communication Program is a written safety program required by Cal OSHA. Haz Comm, for short, helps employees identify chemicals and substances that may cause injury.

Every safety binder must have one. All employees must be trained on the program. The program consists of the following elements:

  • Workplace hazardous material inventory

  • Safety Data Sheets (SDS)

  • Labels and other forms of warning

  • Employee information and training

  • Hazardous non-routine task

  • Pipe labeling

Job Hazard Analysis

Job Hazard Analysis

What is a Job Hazard Analysis (JHA)?

  • A job hazard analysis is a technique that focuses on job tasks as a way to identify hazards before they occur.

  • It focuses on the relationship between the worker, the task, the tools, and the work environment.

  • After a job hazard analysis is completed, the document is kept on record with the safety binder.

What jobs are appropriate for a job hazard analysis?

JHA can be conducted on many jobs in your workplace.

Priority should go to the following types of jobs:

  • Jobs with the highest injury or illness rates

  • Jobs with the potential to cause severe or disabling injuries or illness, even if there is no history of previous accidents

  • Jobs in which one simple human error could lead to a severe accident or injury

  • Jobs that are new to your operation or have undergone changes in processes and procedures

  • Jobs complex enough to require written instructions

Lift Equipment

Lift Equipment

Scissor Lift

Type of platform that can usually only move vertically. The mechanism to achieve this is the use of linked, folding supports in a criss-cross "X" pattern.

Boom Lift / Cherry Picker

Originally used to pick fruits in orchards. Allows employees to work at elevated heights.

Boom Lift / Telehandler

Functions similar to a forklift, but generally for outside terrain use.


Often used in warehouses to lift pallets.


Used to create trenches, excavation or move ground material.


Gradall is a brand name, not a type of lift equipment.

Welding/Brazing - Hot Work

Welding/Brazing - Hot Work

What is Hot Work?

Any work with the use of portable gas, arc welding equipment or high heat equipment for:

  • Welding

  • Brazing

  • Cutting

  • Soldering

  • Grinding

  • Any other similar activities producing a spark, flame, or heat

Hot Work Permit

  • A hot work permit is generally required by the employer or GC. The permit is written and issued by the employer and kept for record keeping. 

  • Whether a permit is required or not, is based on several factors. Describe the hot work you have (or anticipate having) on the Project Management Pre-Construction form.

Personal Protective Equipment (PPE)

All employees performing hot work must use the additional and appropriate personal protective equipment. The appropriate PPE will depend on the type of work and environment. Generally, this includes: helmet, face shield, welder shoes, high heat gloves, and welder jacket.
