Question 1

What is the goal of OSHA's Hazard Communication Program?

Accepted Answer

OSHA's Hazard Communication Program requires employers to inform employees about workplace hazards and provide them with information and training on how to protect themselves. The goal is to ensure that workers know about the different chemicals and substances they may come into contact with at work and how to use them safely. This helps prevent accidents, injuries, and illness in the workplace.

Question 2

How does one determine the hazard potential of a chemical just before it's used in the office?

Accepted Answer

The best way to determine the hazard potential of a chemical just before it's used in the office is by reading the label and the Safety Data Sheet (SDS). The label contains information on the chemical's hazards, which includes pictograms, signal words, and hazard statements. The SDS provides more detailed information about the chemical's properties, potential hazards, safe handling and storage procedures, and emergency response measures. Therefore, it is important to read both the label and the SDS before using any chemical in the workplace. Option A may not always be feasible or practical, while options B and C may not provide accurate or reliable information.

Question 3

Which of the following documents describes the properties and potential hazards of chemicals?

Accepted Answer

Safety Data Sheets (formerly known as Material Safety Data Sheets) describe the properties, potential hazards, and safe handling guidelines for chemicals. The other options (OSHA's Exposure Control Plan, Organization for Safety, Asepsis and Prevention Guidelines, and Bloodborne Pathogens Standard) are documents that provide guidance and regulations for workplace safety, but do not specifically focus on chemicals.

Question 4

The OSHA-required written Hazard Communication Program for each dental office must contain:

Accepted Answer

The OSHA-required written Hazard Communication Program for each dental office must identify the person responsible for implementing the program.

Answer: D 
 A list of all job classifications in which employees in those jobs have occupational exposure is required in the OSHA-required written Hazard Communication Program for each dental office.

A and C are not relevant to the Hazard Communication Program and are instead requirements for an Exposure Control Plan (ECP) for bloodborne pathogens.

Question 5

If a disinfectant that contains hazardous chemicals is purchased in a concentrated form and is then diluted for use and placed in a spray bottle, what must be done to comply with the Hazard Communication Standard?

Accepted Answer

According to the Hazard Communication Standard, any hazardous chemicals that are diluted and placed in a spray bottle must be labeled with the appropriate hazard warnings, name and address of the manufacturer, and the name of the hazardous chemicals. This is to ensure that anyone who handles or uses the disinfectant is aware of its potential hazards and knows how to handle it safely. Option A is incorrect because it is not sufficient to do nothing. Option B is not required, but it may be a good idea to inform the manufacturer. Option C is also not required.

Question 6

Which of the following must be managed according to the Hazard Communication Standard?

Accepted Answer

Amalgam is a chemical substance used in dental practices and must be managed according to the Hazard Communication Standard to ensure safety and proper handling.

Question 7

When was the most recent federal update of OSHA's Hazard Communication Standard?

Accepted Answer

The most recent federal update of OSHA's Hazard Communication Standard was in 2012 when OSHA aligned the standard with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). This update involved changes to the classification, labeling, and safety data sheet requirements for hazardous chemicals, as well as training requirements for employees about the new label elements and pictograms.

Question 8

Who prepares the original SDS?

Accepted Answer

The manufacturer of the chemical is responsible for preparing the original SDS as they have the most comprehensive knowledge about the chemical’s properties and hazards.

Question 9

According to the Hazard Communication Standard, a list of all chemicals in the office should be prepared and cross-referenced to:

Accepted Answer

The Hazard Communication Standard requires that a list of all chemicals in the office be prepared and cross-referenced to the Safety Data Sheets (SDSs). This helps ensure that employees are aware of the hazards associated with the chemicals they are working with, and can take appropriate precautions to protect themselves and others. Cross-referencing the chemicals to the SDSs also makes it easier for employees to find the relevant information they need in case of an emergency.

Question 10

Development of a chemical hygiene plan is part of which OSHA standard?

Accepted Answer

The development of a chemical hygiene plan is a requirement of the Occupational Exposure to Hazardous Chemicals in the Laboratory Standard (also known as the Laboratory Standard) which is enforced by OSHA. This standard requires that laboratories develop and implement a Chemical Hygiene Plan (CHP) that specifies procedures, equipment, personal protective equipment (PPE), and work practices that are capable of protecting employees from the health hazards associated with the chemicals used in the laboratory.

Question 11

OSHA improves safety conditions in the workplace by _____ engineering controls and ____ work practices.

Accepted Answer

OSHA's regulations and standards focus on improving workplace safety by implementing engineering controls (i.e. physical modifications to equipment or machinery) and changing work practices (i.e. adjusting employee behavior and responsibilities). Eliminating or reducing hazards is certainly a consideration, but not the sole focus of OSHA's efforts.

Question 12

The minimal OSHA-accepted label on a hazardous chemical includes a product identifier, a signal word (e.g., danger), a hazard statement, a precautionary statement, the name, address, and phone number of the manufacturer and:

Accepted Answer

The pictogram is required by OSHA to be included on the label of hazardous chemicals to visually communicate the specific hazard(s) associated with the chemical. The other options (B, C, D) are not required elements on the label.

Question 13

What is the central element for compliance with the Occupational Exposure to Hazardous Chemicals in the Laboratory Standard?

Accepted Answer

The central element for compliance with the Occupational Exposure to Hazardous Chemicals in the Laboratory Standard is the Chemical Hygiene Plan (CHP), which outlines procedures, equipment, personal protective equipment, and work practices to ensure the laboratory's safe use of hazardous chemicals. The CHP must cover all employees potentially exposed to hazardous chemicals, including proper labeling, storage, and disposal of hazardous chemicals, and includes provisions for employee training, medical consultation and examination, and record-keeping. The Exposure Control Plan (A) is required for compliance with the Bloodborne Pathogens Standard, and the Hazard Communication Program (D) is required for compliance with the Hazard Communication Standard. The Vaccination Declination Statement (C) is not directly related to compliance with the Occupational Exposure to Hazardous Chemicals in the Laboratory Standard.

Question 14

OSHA recommends solving a potential problem with a hazardous chemical by (1) determining if a problem exists, (2) using engineering controls to attack the problem, (3) adapting work practices to attack the problem, and (4):

Accepted Answer

OSHA recommends using personal protective equipment as a last resort after other methods such as engineering controls and adapting work practices have been attempted to mitigate the hazard.

Question 15

Training of employees is an essential component of a successful HazCom Standard program.Training for all continuing employees is required at the time of hiring, when a new hazard is introduced, and:

Accepted Answer

The HazCom Standard requires that all employees receive training at the time of hiring and when a new hazard is introduced. Additionally, OSHA recommends annual refresher training for all employees to ensure their knowledge and understanding of the hazards in their workplace stay current. Therefore, the best choice is annually (option B).

Question 16

The Hazard Communication Standard requires that employees be informed of the requirements of the standard, any and all operations where hazardous chemicals are present or are used, and the location of the written hazard communication program including the:

Accepted Answer

The location of the written hazard communication program should include a list of hazardous chemicals present and Safety Data Sheets (SDSs), which provide detailed information about the hazards and safe handling of each chemical. The written exposure control plan, vaccination declination document, and emergency action plan may also be important for employee safety, but they are not specifically required by the Hazard Communication Standard.

Question 17

Which federal agency developed the Hazard Communication Standard?
