How to Dress for the Lab? And what about Personal Protective Equipment (PPE)? Video 3

Main ideas / lessons conveyed

• PPE is a primary way to protect yourself in the lab, especially from splashes, impacts, and chemical exposure.
• PPE is not the first line of defense: you should first ensure your clothing is appropriate (proper coverage and safety fit).
• Avoid exposing skin, for example:
  • shorts / short skirts
  • T-shirts that leave arms, legs, and midriff exposed
• Avoid loose or bulky clothing that could:
  • knock over equipment,
  • get dragged through chemical spills,
  • or catch fire near open flames.
• Wear required lab-specific garments when instructed (e.g., lab coats or non-flammable, non-porous aprons), typically worn over correct clothing.
• Wear proper lab shoes to prevent injury from spills/splashes and dropped glassware:
  • shoes must cover heel to toe
  • no sandals, flip-flops, or backless shoes
  • no high heels or wedges
• Manage hair and jewelry:
  • tie back long hair
  • remove dangling jewelry (earrings, necklaces, bracelets)
  • they can tangle in equipment, expose skin/eyes to hazards, or catch fire
• The video emphasizes eye protection as critical:
  • Safety goggles protect against both splashes and impacts
  • Prescription glasses help with impact resistance but don’t protect from liquid/splashes that hit from the side or get behind the lenses
  • typical safety glasses may have a splash guard, but it doesn’t conform closely enough for real splash protection
• Goggles fitting and anti-fogging improve compliance and comfort:
  • choose the correct goggle size
  • adjust the elastic strap for snug (not cutting) fit
  • use an anti-fog soap solution technique

Methodology / instruction list (step-by-step)

1) Before putting on PPE: check your clothing

• Avoid clothing that leaves lots of skin exposed:
  • don’t wear shorts, short skirts, or T-shirts that expose arms, legs, and midriff
• Choose clothing that protects:
  • arms, legs, and midriff (applies to all students)
• Avoid loose/bulky clothing:
  • don’t wear items that could be knocked into or dragged through equipment/spills
  • avoid clothing that could catch fire near open flames
• Follow teacher requirements for additional garments:
  • wear lab coats or aprons when required
• Prefer aprons that are:
  • non-flammable
  • non-porous

2) Choose safe footwear

• Ensure shoes:
  • cover feet from heel to toe
• Prohibited:
  • sandals, flip-flops, backless shoes
  • high heels and wedges

3) Prepare hair and jewelry

• Tie back long hair
• Remove dangling jewelry:
  • earrings, necklaces, bracelets
• Purpose:
  • prevent entanglement and exposure to hazards
  • reduce risk of catching fire around flames

4) Wear correct eye protection (and use the right goggles)

• Understand the hierarchy:
  • Chemical splash goggles (“safety goggles”) are required for full splash + impact protection
  • prescription glasses are better than nothing, but not sufficient for splashes/drips
  • construction-style safety glasses may help with some impact and partial splash features, but still don’t fully protect
• Goggles features and usage:
  • come in different sizes/colors
  • use adjustable elastic straps for a close fit
  • goggles are vented; venting plugs should never be removed
• If you wear prescription glasses or contact lenses:
  • chemical splash goggles are designed to fit over prescription glasses
  • contact lenses must also be worn with chemical splash goggles (per the video) to reduce the risk of chemicals getting into eyes
  • soft contact lenses may absorb chemical vapors through goggles vents; a teacher may recommend special unvented goggles

5) Make goggles fit correctly (comfort steps)

• Fit adjustment checklist:
  • pick the appropriate goggle size
  • if fit is off, ask for a smaller or larger size
  • adjust using the elastic strap (snug but not cutting into cheeks)
• Fit diagnostics:
  • deep marks after removal → too tight
  • goggle movement/freedom → too loose

6) Reduce fogging

• Anti-fog trick:
  • rub a little soap solution on the inside of the lenses
  • polish lenses dry before putting goggles on

7) Overall PPE reminder

• Wearing the appropriate PPE is essential for lab activities.
• “Suit up” with the correct gear for what you’re doing.
