Chapter 290, Health and Safety Services
Section 86, Hazardous Operations
Approved: 4/2/09
Supersedes: 4/8/05

Responsible Department: Environmental Health and Safety
Source Document: California Code of Regulations, Title 8

I. Purpose

This section establishes responsibilities and procedures for the safe management of certain physically hazardous operations at UC Davis facilities, including entry into confined spaces, use of oxyacetylene welding equipment, use of portable torches for soldering and brazing, operation of forklift trucks, and operations requiring lockout/tagout, fall protection, and excavation, trenching, and shoring.

II. Definitions

A. Confined space--as defined by Cal-OSHA, a space that has all three of the following characteristics: is large enough and configured such that an employee can enter and perform work, has limited openings for entry and exit, and is not designed for continuous employee occupancy. Two main hazards associated with confined spaces are atmospheric hazards and physical hazards. Atmospheric hazards typically involve problems with the air in a space (i.e., lack of oxygen, the presence of other gasses in the space, insufficient ventilation, etc.). Physical hazards are those caused either by equipment (rotors, sparks, moving machinery, energized systems, etc.) or by other dangerous conditions (slippery surfaces, heat, noise, lighting, vermin, insects, etc.). Examples of confined spaces include silos, tanks, vats, boilers, ducts, sewers, manholes, pipelines, vaults, bins, tubs, excavations, trenches, pits, wet wells, fireboxes, boxcars, and other confining structures.

B. Excavation, trenching, and shoring

1. Excavation--any man-made cut, cavity, trench, or depression in an earth surface, formed by earth removal.

2. Trench--a narrow excavation (in relation to its length) made below the surface of the ground. In general, the depth is greater than the width, but the width of a trench is not greater than 15 feet.

3. Shoring--a structure such as a metal hydraulic, mechanical, or timber shoring system that supports the sides of an excavation and is designed to prevent cave-ins.

4. Benching--A method of protecting employees from cave-ins by excavating the sides of an excavation to form one or a series of horizontal levels or steps, usually with vertical or near-vertical surfaces between levels.

5. Competent person--one who is capable of identifying existing and predictable hazards in the surroundings or working conditions that are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them. The competent person must be able to demonstrate the following: the ability to recognize all possible hazards associated with excavation work and to test for hazardous atmospheres; knowledge of the current safety orders pertaining to excavation, trenching, and shoring; the ability to analyze and classify soils; knowledge of the design and use of protective systems; and the authority and ability to take prompt corrective action when conditions change.

C. Fall protection--approved personal fall arrest systems, personal fall restraint systems, or positioning device systems. Cal-OSHA requires fall protection by those employees whose work exposes them to falling in excess of 7.5 feet from: the perimeter of a structure, unprotected sides and edges, leading edges, through shaftways and openings, sloped roof surfaces steeper than 7:12 (about 30 degrees), or other sloped surfaces steeper than 40 degrees.

D. Forklift truck--a mobile power-driven truck (gasoline, propane, electric, etc.) used for hauling, pushing, lifting, or tiering materials where normal work is normally confined within the boundaries of a place of employment.

E. Lockout/tagout--techniques used to prevent hazardous energy from injuring or killing workers. In a lockout, a padlock is placed on a disconnected switch, circuit breaker, valve handle, or other energy-isolating mechanism that is in the off position. In a tagout, a written warning tag is placed on the energy-isolating device that is in the off or closed position.

F. Oxyacetylene welding--commonly referred to as gas welding, a process that relies on combustion of oxygen and acetylene within a hand-held torch or blowpipe. The chemical action of the oxyacetylene flame can be adjusted by changing the ratio of the volume of oxygen to acetylene.

G. Soldering and brazing-- joining processes where parts are joined without melting the base metals.

1. Soldering filler metals melt below 840°F and is commonly used for electrical connection or mechanical joints.

2. Brazing filler metals melt above 840°F and is only used for mechanical joints due to the high temperatures involved.
