    Study Notes

    Regulated Waste

    • Regulated waste includes materials such as blood-soaked gauze, human tissue, and scalpel blades.

    Expired Products

    • Products that have surpassed their expiration date must be disposed of immediately to prevent risks.

    Latex Gloves and Chemicals

    • Latex gloves offer inadequate protection against chemicals due to degradation when exposed to chemical disinfectants.

    Safety Data Sheets (SDS)

    • SDS should be organized in binders for easy employee access.
    • Section 6 of the SDS addresses accidental release measures.

    Chemical Exposure Effects

    • Chemical exposure can damage lungs and also impact the kidneys, brain, and liver.

    Chronic vs Acute Chemical Toxicity

    • Chronic toxicity results from lower levels of chemicals over a longer duration, contrasting with acute toxicity, which arises from higher levels over a short time.

    Hazard Communication Program Training

    • Chemical training for employees includes hazardous chemicals usage, required Personal Protective Equipment (PPE), and safe handling and disposal methods.

    Hazard Communication Program Requirements

    • The written program in the Hazard Communication Program details procedures for responding to chemical emergencies.
    • Training is mandatory for employees annually.

    Hazardous and Regulated Waste

    • Regulated waste requires special disposal methods and includes infectious materials.
    • Examples of waste that do not classify as hazardous include human tissue.

    Waste Container Protocols

    • Waste containers for potentially infectious materials must bear the biohazard symbol.
    • All sharps containers must be leak-proof, puncture-resistant, and closable.
    • Scrap dental amalgam must be stored in designated, dry, airtight containers.

    Chemical Spill Response

    • Immediate symptoms such as dizziness, headache, nausea, and vomiting indicate acute chemical toxicity.
    • For mercury spills, use a mercury spill kit with protective gear including a mask and utility gloves.

    SDS Information Requirements

    • SDS must provide hazard identification, accidental release measures, and composition/information on ingredients.

    Chemical Labeling

    • When transferring chemicals to new containers, it is critical to label them appropriately as per the established training guidelines.

    Environmental Safety

    • Good ventilation is essential in various areas within a dental environment, excluding the reception area.
