When you hear the evacuation alarm, the correct response is to evacuate immediately to the emergency assembly point. This is because the purpose of an evacuation alarm is to alert individuals of an imminent danger or emergency situation. Stopping to get belongings or calling a supervisor can waste valuable time and potentially put oneself and others at risk. Waiting for further instruction may also delay the evacuation process. Therefore, it is crucial to prioritize personal safety and quickly move to the designated assembly point for further guidance and assistance.

RPN stands for Risk Priority Number. This is a numerical value used in risk management to prioritize risks based on their severity, likelihood, and detectability. It is calculated by multiplying the severity, likelihood, and detectability ratings of a risk. The higher the RPN, the higher the priority of the risk, indicating that it requires immediate attention and mitigation.

Appropriate gloves can protect hands from various hazards such as contacting hot materials or surfaces, cuts, and electric shocks. These gloves are designed to provide insulation and a barrier between the hands and the potential dangers. They can withstand high temperatures, have cut-resistant properties, and offer electrical resistance. Therefore, wearing appropriate gloves ensures safety and reduces the risk of injuries or harm when handling hot materials, sharp objects, or working with electricity.

When exposed to hazards from flying particles, both eye and face protection are needed. This is because flying particles can cause damage not only to the eyes but also to the face. Eye protection alone may not be sufficient to protect against larger particles that can cause injuries to the face. Therefore, it is important to wear both eye and face protection to ensure comprehensive protection from flying particles.

Driving in speed limits is not dangerous while driving because it ensures that the driver is driving at a safe and controlled speed, reducing the risk of accidents. Speed limits are set based on various factors such as road conditions, traffic flow, and visibility, to ensure the safety of all road users. By adhering to speed limits, drivers can maintain better control over their vehicles and have more time to react to unexpected situations, minimizing the chances of collisions and injuries.

The plant head is the person who has the authority to authorize a deviation from standard procedures. They are responsible for overseeing the operations of the plant and making decisions regarding any changes or exceptions to the standard protocols. As the highest-ranking official in the plant, they have the knowledge and expertise to evaluate the situation and determine if a deviation is necessary and appropriate. The plant head's authorization ensures that any deviations are properly evaluated and approved, maintaining the overall efficiency and effectiveness of the plant's operations.

TLV stands for Threshold Limit Value. This term is commonly used in the field of occupational health and safety to refer to the maximum concentration of a chemical that workers can be exposed to without experiencing adverse effects. TLV is typically expressed as a time-weighted average over an 8-hour workday. It helps employers and regulatory bodies establish guidelines to protect workers from the potential hazards of chemical exposure in the workplace.

The given correct answer is "Unsafe act." This suggests that the example provided in the question is an instance of an unsafe act. An unsafe act refers to any action or behavior that poses a risk to oneself or others, potentially leading to accidents or injuries. This implies that the situation described in the question involves an action or behavior that is not in accordance with safety protocols or guidelines, thereby creating a hazardous condition.

The correct answer is 8 pm to 5 am. This time period is defined as "odd hours" according to the TML Travel Policy. It is recommended to avoid driving during this time as it is generally considered to be late at night and early in the morning when visibility may be reduced and there is a higher risk of accidents.

Flashback arresters are safety devices that are used to prevent the occurrence of a flashback in a gas cutting process. A flashback is a dangerous situation where the flame travels back into the gas supply line, potentially causing an explosion. To prevent this, flashback arresters are installed on all components of the gas cutting process, including the L.P.G cylinder, oxygen cylinder, and cutting torch. By doing so, the flashback arresters ensure the safety of the entire system by stopping the flame from traveling back and causing any harm.

According to the factory rules, pressure vessels need to be inspected externally every six months. This means that every half year, the pressure vessels must undergo an inspection to ensure their safety and functionality. This regular inspection schedule helps to identify any potential issues or damages that may have occurred over time, allowing for timely repairs or maintenance to be carried out. By conducting these inspections every six months, the factory can ensure that the pressure vessels are in compliance with safety regulations and minimize the risk of accidents or failures.

According to the ESMS Standard, any voltage exceeding 50V is deemed to be a lethal shock hazard. This means that any electrical current above this threshold has the potential to cause severe injury or even death if it comes into contact with a person. Therefore, it is crucial to exercise caution and implement appropriate safety measures when dealing with voltages exceeding 50V.

The true purpose of a "Permit to Work System" in an industry is to authorize "Non routine hazardous activities." This system ensures that any activity that poses a potential risk to the safety of workers or the environment is properly authorized and controlled. By obtaining a permit to work, employees are made aware of the potential hazards associated with their tasks and are required to follow specific safety procedures. This helps to prevent accidents, injuries, and damage to property, ultimately promoting a safer work environment.

Mechanical foam fire extinguishers are used to put out fires caused by flammable liquids. This type of extinguisher works by forming a blanket of foam over the burning liquid, which helps to smother the fire and prevent the release of flammable vapors. Carbon dioxide fire extinguishers are typically used for electrical fires, while water fire extinguishers are effective for fires involving ordinary combustible materials. Dry chemical fire extinguishers are versatile and can be used for different types of fires, but they may not be as effective for flammable liquid fires as mechanical foam extinguishers.
