Introduction to Hazardous and Toxic Chemical Management (B3)
📌 Management of hazardous and toxic chemicals (B3) is crucial for Occupational Safety and Health (K3).
👷 Accidents often stem from a lack of knowledge in recognizing and handling B3, including negligence or not following safety procedures, such as using Personal Protective Equipment (PPE).
⚠️ B3 incidents can cause direct harm to workers and lead to environmental pollution.

Hazards and Effects of B3 Chemicals
🔥 B3s can cause fire, explosion, poisoning, and irritation.
💥 Explosions result from rapid reactions, large gas production, or uncontrolled high-pressure gas release; fires involving flammable solvents can also trigger explosions.
🤢 Poisoning occurs when chemicals enter the body: Acute poisoning is a large dose in a short time (potentially fatal, e.g., CO or HCN), while chronic poisoning is a small dose over a long period.
👁️ Irritation involves inflammation of surfaces like skin, eyes, or respiratory tracts caused by corrosive chemicals (e.g., Hydrochloric Acid).

B3 Management System (Planning, Organizing, Executing, Controlling)
📋 Planning aims to avoid procuring chemicals unnecessary for planned activities, ensuring needs are met without excess accumulation, covering procurement, storage, and usage.
🧪 B3s are classified into two main groups: Hazardous Chemicals (reactive, flammable, explosive, water/acid-reactive) and Toxic Chemicals (affecting health via inhalation, ingestion, or skin contact).
⚙️ Organizing involves defining roles (manager, user, supervisor) and establishing strict storage requirements based on chemical properties (e.g., toxic substances need cool, ventilated, separated storage).

Storage Requirements and Chemical Interactions
🛑 Specific storage rules must be followed: flammable materials need separation from heat sources, corrosives in closed, labeled containers, and explosive materials in cool, dark areas.
🧪 Chemical interactions must be understood:
- Environment interaction (heat/sparks) can cause fires with flammable solvents.
- Container interaction (e.g., concentrated acids destroying the container) leads to dangerous secondary reactions.
- Material interaction (e.g., oxidizers and reducers causing explosions) necessitates physical separation during storage.
🔥 For materials reactive with water (like alkali metals), use non-water-based fire extinguishers (e.g., CO₂, dry powder).

Implementation and Control
📜 Implementation requires adherence to established procedures detailed on chemical labels (name, formula, physical/chemical properties, hazards).
🛠️ Handling toxic/corrosive materials must occur in specialized areas like fume hoods, using appropriate PPE (respirators, resistant gloves/lab coats).
🔍 Control/Evaluation involves inspections and audits from planning through execution to ensure adherence to safety policies and procedures regarding B3 handling, storage, and use.

Key Points & Insights
➡️ Strict adherence to K3 principles is paramount when managing B3 chemicals to prevent accidents and environmental harm.
➡️ Properly categorize and segregate B3 materials during storage based on their reactivity (e.g., separate oxidizers from reducers, keep corrosives away from incompatible materials).
➡️ All handling procedures (mixing, heating, transferring) for toxic/corrosive substances must be performed within designated areas (like fume hoods) using specific, material-appropriate PPE.
