Communicating a Hazard in the Workplace

Biohazard Sign

Primary Methods of Communicating: Signs and Labels

Signs and labels that alert you to the presence of potentially infectious material and the risk of exposure are vital to a workplace with occupational exposure to potentially infectious materials.

Be sure you are aware of and abide by all signs and labels signaling hazards and hazardous material.

Signs should have a fluorescent orange or orange-red background with a black "biohazard" symbol in the foreground.

Labels must contain the biohazard symbol and must have the word "Biohazard" written on them.

Biohazard bag
Use these red biohazard bags to dispose of solid or liquid items contaminated with blood or other potentially infectious materials (OPIM).

A biohazard label or sign should be attached to each object or container of contaminated material by string, wire, adhesive, or another method that prevents loss or unintentional removal of the label or sign.

When red bags or containers with the biohazard symbol on them are used, a sign or label is not necessary.

Also, when medical laboratory personnel are drawing and testing blood samples, the individual containers housing potentially infectious materials do not need to be labeled.

Properly indicating contaminated material using labels and signs will greatly reduce the risk of accidental exposure to the contaminated material. It is important to maintain appropriate container labeling at all times.

Annual training must be conducted for all employees with occupational exposure.

1. Signs used to warn of potentially infectious materials should have a _______.

a. fluorescent yellow background with a black "lightning bolt" symbol in the foreground
b. fluorescent red background with a black "radioactivity" symbol in the foreground
c. fluorescent orange or orange-red background with a black "biohazard" symbol in the foreground
d. red background with a black "skull" symbol in the foreground

Information and Training

Students at computer
If using computer based training (CBT), there must be an opportunity for students to ask questions.

All employees (including part-time and temporary employees) with occupational exposure in the organization should participate in a training program that is provided at no cost during working hours. The training materials used should be appropriate in content and vocabulary to the educational and literacy levels and are conveyed in the language of the employees.

The training materials should clearly state the objectives of the training. Trainers should be knowledgeable in the subject matter covered by the training program as it relates to the workplace. All employees should have an opportunity for interactive questions and answers with the person(s) conducting the training. If computer or online training is used, it should provide an opportunity for a person knowledgeable about the training material to be available to answer questions.

a. it must require an 80% passing score on exams
b. it must be conducted during normal work hours
c. it must be paid for by the employer
d. it must be conveyed in the language of employees

Scenario

Jennifer works for a computer parts manufacturer. One of her job duties is to perform housekeeping tasks for her section of the warehouse. During her last shift an employee was injured and required first aid treatment, producing contaminated clothing and personal protective equipment. This contaminated material needs to be labeled and disposed of.

How should Jennifer dispose of this contaminated material?

Jennifer's Actions

Jennifer needs to use appropriate personal protective equipment while working with the contaminated materials.

She must also place the contaminated material in a leak-proof bag that is labeled with the symbol and word "Biohazard".

Jennifer should then dispose of the bag based on her employer's exposure control plan.
