Which of the following data is included on a material safety data sheet?
The SDS includes information such as the properties of each chemical; the physical, health, and environmental health hazards; protective measures; and safety precautions for handling, storing, and transporting the chemical.
What is the best way to protect yourself when working near moving vehicles?
What is the best way to protect yourself when working near moving vehicles and equipment? Wear a reflective or high-visibility vest.
What is the most common form of hazardous energy control?
Electrical energy
Electrical energy is the most common form of energy used in workplaces. It can be available live through power lines or it can also be stored, for example, in batteries or capacitors.
What is the most common cause of death for equipment operators?
The most common cause of death for equipment operators is equipment rollover.
What is the most common grounding system?
2. Solidly grounded. This type of grounding system is most commonly used in industrial and commercial power systems, where grounding conductors are connected to earth ground with no intentional added impedance in the circuit.
What is the importance of material safety data sheet?
The MSDS lists the hazardous ingredients of a product, its physical and chemical characteristics (e.g. flammability, explosive properties), its effect on human health, the chemicals with which it can adversely react, handling precautions, the types of measures that can be used to control exposure, emergency and first …
What is an example of an unsafe condition on a job site?
Examples of Unsafe Working Conditions in the Workplace: Inadequate or malfunctioning warning systems (or lack of such a system) Flooring that has debris, water, or slippery substances that create a hazard. Blocked safety exits. Equipment that is not maintained or not working properly.
What are the four types of stored energy?
Stored energy can have many forms, including gravitational potential energy, pressurised gases and liquids, stored mechanical energy, and stored electrical energy.
What material is higher than do not stack?
To reduce the risk of workers being hurt or killed by falling materials, do not stack materials higher than a what height-to-base ratio. HazCom classifies all paint, concrete, and wood dust as what materials. Hazardous. Under HazCom, if you spot a hazard on your job site you must what.
What are circuit breakers and disconnect switches are examples of?
Explanation: Energy-isolating devices are used to restrict the flow or transmission of energy (electricity in this case) by physical means therefore it includes manually operated devices such as a manually operated electrical circuit breakers and disconnect switches.
What are the 2 types of grounding?
There are two kinds of grounding: (1) electrical circuit or system grounding, and (2) electrical equipment grounding. Electrical system grounding is accomplished when one conductor of the circuit is intentionally connected to earth.
How do you stop grounding properly?
A common method of ensuring the ground remains intact is through the use of a pigtail connection. To make a pigtail connection, take both ground wires and join them with a 6-inch wire of the same color that has been stripped on either end. Hold all three tightly and bind them together with a wire connector.
What are the core characteristics of an SDS document?
An SDS (formerly known as MSDS) includes information such as the properties of each chemical; the physical, health, and environmental health hazards; protective measures; and safety precautions for handling, storing, and transporting the chemical.
