1.
Never use oil on cylinders, regulators, connections, or hoses.
Correct Answer
A. True
Explanation
Oil should never be used on cylinders, regulators, connections, or hoses because it can cause damage and compromise the safety of the equipment. Oil can deteriorate rubber components, interfere with the proper functioning of regulators, and increase the risk of leaks or fires. Therefore, it is important to avoid using oil on these parts to ensure their proper operation and safety.
2.
Eye protection must be worn at all times in the welsing shop.
Correct Answer
A. True
Explanation
Eye protection must be worn at all times in the welding shop to ensure the safety of individuals working in the shop. Welding processes involve intense heat, bright light, and the release of harmful particles and gases, which can cause serious eye injuries and even permanent damage. Wearing eye protection, such as safety glasses or welding helmets with proper filters, helps to prevent these hazards from affecting the eyes. Therefore, it is necessary to wear eye protection in the welding shop at all times to minimize the risk of eye injuries.
3.
Contact lenses can be melted to the cornea of the eye by welding sparks.
Correct Answer
B. False
Explanation
Contact lenses cannot be melted to the cornea of the eye by welding sparks. Contact lenses are made of materials such as silicone hydrogel or soft plastic, which have high melting points and are designed to withstand the normal conditions of the eye. Welding sparks do not generate enough heat to melt the contact lenses or cause them to adhere to the cornea. Therefore, the statement is false.
4.
Always check work area to make sure that they are ______________
Correct Answer
B. Safe to work in
Explanation
The work area should always be checked to ensure that it is safe to work in. This means that it should be free from any hazards or potential dangers that could cause harm to the workers. This includes ensuring that the area is clean and dry, as wet or slippery surfaces can pose a risk of accidents and injuries. By checking that the work area is safe to work in, it helps to create a secure and suitable environment for the workers to carry out their tasks effectively and without unnecessary risks.
5.
Always keep welding equipment in good working condition
Correct Answer
A. True
Explanation
Keeping welding equipment in good working condition is important for several reasons. First, it ensures the safety of the welder and those around them. Faulty equipment can lead to accidents and injuries. Second, well-maintained equipment performs better, resulting in higher quality welds. Regular maintenance and inspections can prevent breakdowns and keep the equipment functioning optimally. Lastly, proper maintenance extends the lifespan of the equipment, saving money on repairs or replacements. Therefore, it is crucial to always keep welding equipment in good working condition.
6.
Never weld, cut, or grind near _________________
Correct Answer
A. Flammable material
Explanation
Welding, cutting, or grinding near flammable material can be extremely dangerous as it can lead to sparks or heat that can ignite the flammable material and cause a fire or explosion. It is important to always ensure a safe distance from any flammable material when performing these tasks to prevent accidents and ensure personal safety.
7.
Welsing work areas should always be ____________ and safe.
Correct Answer
A. Clean
Explanation
Welsing work areas should always be clean and safe in order to maintain a healthy and productive environment. A clean work area helps to prevent the spread of germs and bacteria, reducing the risk of illness and promoting overall well-being. It also allows for better organization and efficiency, as clutter and mess can lead to distractions and hinder productivity. Additionally, a clean work area promotes a positive image and professionalism, both for employees and visitors.
8.
You should wear only a shade #12 dark lens when welding.
Correct Answer
B. False
Explanation
Wearing only a shade #12 dark lens when welding is not recommended. The appropriate shade of lens to wear during welding depends on the type of welding being performed. Different welding processes produce different levels of brightness and UV radiation, requiring different shades of lens. For example, shielded metal arc welding typically requires a shade #10-14 lens, while gas metal arc welding may require a shade #9-13 lens. Therefore, it is important to choose the correct shade of lens based on the specific welding task to ensure proper eye protection.
9.
Only safety glasses need to be worn when grinding, chipping, or cutting.
Correct Answer
B. False
Explanation
The statement is false because in addition to safety glasses, other protective gear such as gloves, face shields, and ear protection may also be required when grinding, chipping, or cutting. Different tasks may present different hazards, so it is important to assess the specific risks and wear appropriate protective equipment accordingly.
10.
Horseplaying is allowed only when you are not welding.
Correct Answer
B. False
Explanation
The statement implies that horseplaying is allowed as long as you are not welding. However, this contradicts common safety protocols, as horseplaying can be dangerous and distracting in any situation. Therefore, the correct answer is False, indicating that horseplaying is not allowed even when you are not welding.
