D873: Laboratory Safety

D873 Laboratory Safety is a short, practical course in WGU's science education programs.

WGU describes it as equipping learners with safety knowledge and skills for laboratories, classrooms and field settings, including safety protocols, legal responsibilities and effective teaching strategies for safety.

It is small but high-stakes, because a teacher's decisions affect students' physical safety. Rubrics reward specifics: named hazards, named controls, and clear lines of responsibility. General statements such as "follow safety rules" rarely satisfy them.

What D873 Covers

An earlier WGU guidebook lists a competency about knowledge of laboratory safety, potential hazards and educator responsibilities. The themes below follow the course description.

Key Concepts Explained

Identify, Assess, Control

Safe planning follows a simple sequence: identify the hazard, assess the likelihood and severity of harm, then apply controls in order of effectiveness: remove or substitute the hazard, use engineering controls, set procedures, and finally protective equipment.

Duty of Care

Teachers are responsible for reasonable supervision, instruction and preparation. Documenting training, checking equipment and knowing emergency procedures are part of meeting that duty.

Emergency Planning

Know what you will do, who you will call and where equipment is. Practice it, because stress makes improvization unreliable.

Typical Assignments and How to Approach Them

WGU's guidebook does not list task prompts. The table describes kinds of work this content points to. Follow your own instructions.

A Study Approach That Works

1. Learn the hazard categories. Chemical, biological, physical, fire and electrical.
2. Practice the sequence. Apply identify, assess, control to three activities.
3. Read your own district or state guidance. It often shapes expectations.
4. Write a sample emergency plan. Keep it to one page.

Where Students Get Stuck

• Vagueness. Name the hazard and the specific control.
• Missing legal duties. State what the educator must do and why.
• Ignoring field settings. Outdoor work brings weather, terrain and transport issues.
• Forgetting to teach safety. The course includes how you instruct students.

Self-Check Questions

Check your safety plan against these questions.

• Have I named each hazard and who could be harmed?
• Are controls ordered from most to least effective?
• Who is responsible for each step, and how will it be recorded?
• What will students be taught, and how will I check they understood?
• What is the emergency procedure, and who does what?

Study Tips for D873

• Use a hazard table with hazard, harm, control and responsible person.
• Name specific equipment, such as eyewash stations and fume hoods.
• Describe how you will check students understand the rules.
• Keep emergency steps in order.
• Check your local requirements; they vary by state and district.

How We Help with D873

Send the task instructions, the scenario, the rubric and your draft. A tutor can explain risk assessment with new examples, review your plan for gaps, edit your writing for clarity, or prepare a custom response on a different activity for you to study. Our lab report guide may also help with lab write-ups.
