### 02. Building Materials and Fasteners (27102) Lesson Objective 1: Identify safety hazards and precautions associated with wood, concrete, steel, and composite building materials. In chapter order: a. **Describe the focus four and explain how to reduce hazards associated with handling carpentry materials.** Focus Four in Construction Safety ================================= 1. ​**Falls:** These are the most common cause of fatalities. Falls occur when workers lose their balance or fall from heights. 2. ​**Struck-by Hazards:** These incidents happen when workers are hit by objects, such as falling tools or materials. 3. ​**Caught-in or Caught-between Hazards:** These accidents involve workers being caught in or between machinery, equipment, or collapsing structures. 4. ​**Electrical Hazards:** Electrocution occurs when workers encounter live electrical circuits or equipment. - To abate these hazards, it is essential to be constantly alert to job conditions and follow safety protocols. - Implementing safety measures such as proper fall protection, securing tools and materials, using machinery safely, and ensuring electrical safety can significantly lower the risk of these deadly accidents. **Identify safety hazards and precautions associated with wood, concrete, steel, and composite building materials.** ==================================================================================================================== Hazard Reduction for Carpentry Materials Handling ================================================= Here are some *Key Points* to consider: 1. Personal Protective Equipment (PPE) ----------------------------------- - **Gloves:** Wear gloves to prevent splinters, cuts, and scrapes when handling wood. However, avoid wearing gloves around rotating or moving equipment to prevent them from getting caught. - **Eye Protection and Dust Masks:** When cutting treated lumber, always wear eye protection and a dust mask to protect against harmful chemicals and sawdust. 2. Proper Lifting Techniques ------------------------- - Plan your task before lifting materials. - Use proper lifting techniques to avoid back injuries. - Do not manually pile lumber more than 6 feet high to prevent it from falling. 3. Material Storage ---------------- - Stack lumber securely to prevent it from falling or sliding. - Place lumber flat on the ground or use short 2x4s at a 90-degree angle to keep it off the ground. - Follow local regulations for the disposal of treated lumber and never burn it due to hazardous ash. 4. Job Hazard Analysis ------------------- b. **Explain the benefits of a job hazard analysis.** Benefits of Job Hazard Analysis (JHA) ===================================== Here are the *Primary* advantages: 1. ### Recognition of Hazardous Conditions: - JHAs help identify and reduce workplace hazards, ensuring a safer environment for employees and compliance with OSHA standards. 2. ### Better Communication: - By involving employees and supervisors in the analysis, JHAs foster improved communication and collaboration, leading to the discovery of potential safety hazards. 3. ### Job Safety Standards Compliance: - Regular JHAs ensure adherence to OSHA standards, providing protection from legal and financial penalties. 4. ### Consistency of Routines: - Breaking down tasks into individual steps ensures that routines are reviewed and applied consistently, promoting a systematic approach to safety. 5. ### Pre-Planning Tool: - JHAs can be used during job planning to review tools, materials, equipment needs, staffing requirements, job duration, and quality concerns, ensuring safety is integrated into the job from the start. - By addressing these aspects, JHAs contribute to creating a proactive safety culture, preventing accidents, and ensuring a well-organized and hazard-free work environment. General Safety Precautions -------------------------- - **Planning and Awareness:** - Always plan and look for potential hazards. - Accidents are often due to *lack of planning*, *carelessness*, and *unsafe practices*. - **Weather Conditions:** - *Monitor* and *discuss* changing weather conditions as they can impact jobsite safety.
