Critical Safety Procedures and Hazard Controls

This document outlines the critical safety procedures, hazard controls, and emergency response protocols necessary for today's planned activities. It also details the required Personal Protective Equipment (PPE) to ensure worker safety and regulatory compliance.

Hazard Identification and Risk Assessment

A comprehensive site evaluation must be performed to identify potential hazards and determine appropriate safety and health control procedures. This evaluation should be conducted by a qualified person before site entry to select suitable employee protection methods. A more detailed evaluation should follow immediately after initial site entry to assess specific site characteristics. [3]

The preliminary and detailed surveys should identify conditions that may pose inhalation or skin absorption hazards that are immediately dangerous to life or health (IDLH), or other conditions that may cause death or serious harm. Examples include confined space entry, explosive or flammable situations, vapor clouds, or areas with biological indicators. [2]

Risk identification involves determining the risks associated with identified hazardous substances and informing employees of these risks. Considerations include exposures exceeding permissible limits, IDLH concentrations, potential skin and eye irritation sources, explosion sensitivity, flammability ranges, and oxygen deficiency. [8] [8]

Hazard Controls

Hierarchy of Controls

The hierarchy of controls should be followed to minimize or eliminate hazards. This includes:

• Elimination: Removing the hazard completely.
• Substitution: Replacing a hazardous substance or process with a less hazardous one.
• Engineering Controls: Using enclosures, machine guards, or worker booths to prevent contact with the hazard.
• Administrative Controls: Modifying work procedures, providing training, and implementing safety policies.
• Personal Protective Equipment (PPE): Providing and ensuring the correct use of PPE as a last line of defense.

Site Control Program

A site control program must be implemented to control employee exposure to hazardous substances before cleanup work begins. This program should be developed during the planning stages and modified as necessary. Key elements include: [9] [9]

• A site map indicating the location of hazards and control measures.
• Clearly defined site work zones to segregate contaminated and clean areas.
• Implementation of a buddy system to ensure continuous communication and support between workers.
• Effective site communication methods, including alerting means for emergencies.
• Standard operating procedures (SOPs) or safe work practices for all tasks.
• Identification of the nearest medical assistance facilities and emergency contact information.

Good Housekeeping

Good housekeeping practices are essential to prevent the accumulation of hazardous materials and conditions. This includes regular cleaning, proper material storage, and waste disposal. [7]

Personal Hygiene

Personal hygiene practices are crucial for minimizing exposure to hazardous materials. These practices include: [1]

• Washing hands thoroughly after handling materials and before eating, drinking, or smoking.
• Avoiding touching the lips, nose, and eyes with contaminated hands.
• Prohibiting smoking, drinking, chewing gum, or eating in work areas; these activities should only be permitted in designated clean areas.
• Ensuring hazardous products are not stored in the same refrigerator as food items.

Emergency Response Procedures

Emergency Preparedness

Being prepared for emergencies involves ensuring that necessary equipment and supplies are readily available and that employees know what to do during unplanned events such as releases, spills, fires, or injuries. Emergency response procedures should be written, and employees should regularly practice their emergency response skills. [1]

Emergency Response Plan Elements

The emergency response plan should address the following elements:

• Pre-emergency planning to anticipate potential incidents.
• Clearly defined personnel roles, lines of authority, and communication protocols.
• Emergency recognition and prevention measures.
• Safe distances and places of refuge.
• Site security and control procedures.
• Evacuation routes and procedures.
• Decontamination procedures.
• Emergency medical treatment and first aid protocols.
• Emergency alerting and response procedures.
• Procedures for handling emergency incidents.
• Critique of the response and follow-up actions.
• PPE and emergency equipment requirements.

Incident Command System (ICS)

An Incident Command System (ICS) should be implemented to effectively control and manage operations during an emergency. The senior official responding to the incident is in charge of the ICS. The ICS helps to reduce confusion, improve safety, organize and coordinate actions, and facilitate effective management of the incident. [4] [4]

Emergency Equipment and Supplies

A current inventory list of all emergency equipment and supplies should be maintained, including maintenance and decontamination procedures. Equipment should be tested as specified by the manufacturer, and equipment and supply needs should be reviewed when changes occur. Contact lists for suppliers of emergency equipment and supplies should be maintained, updated, and readily available. [6]

Personal Protective Equipment (PPE)

PPE Program

A comprehensive PPE program should be in place, including hazard identification, medical monitoring, environmental surveillance, selection, use, maintenance, and decontamination of PPE, and associated training. The written PPE program should include policy statements, procedures, and guidelines, with copies available to all employees and a reference copy at the worksite. Technical data, maintenance manuals, and relevant regulations should also be maintained. [4] [4]

PPE Selection

The selection of appropriate PPE must be based on the specific hazards present at the workplace. Examples of PPE include: [5]

• Respiratory protection
• Head protection
• Skin protection (e.g., coveralls, aprons, full body suits)
• Gloves
• Eye protection (e.g., face shields, goggles)
• Foot protection
• Hearing protective devices (e.g., earplugs, earmuffs)

PPE Usage

PPE should be used in conjunction with other protective methods, and its effectiveness should be evaluated periodically. Over-protection, as well as under-protection, can be hazardous and should be avoided where possible. [4] [4]

Training and Education

Employee education and training are critical for ensuring work is conducted safely. Training must cover how to do the job safely, the hazards and risks of the job, and the controls in place to protect them. Workers must also be provided with information on how to protect themselves and co-workers. [7]

Training Program Elements

The training program should include:

• Names of personnel responsible for site safety and health.
• Safety, health, and other hazards present on the site.
• Proper use of personal protective equipment.
• Work practices to minimize risks from hazards.
• Safe use of engineering controls and equipment on the site.
• Medical surveillance requirements, including recognition of symptoms and signs of overexposure.
• Contents of the site safety and health plan.

Review and Evaluation of Controls

It is important to determine the effectiveness of implemented control methods and adjust as required. Controls must not create new hazards. The hazard and the control method should be monitored to ensure the control is working effectively and that exposure to the hazard is reduced or eliminated. [5] [5]
