A3: Skin Hazard

Question 1

Symptoms of burns?

Answer 1

Blister, pain, erythema and charred skin

Question 2

What are the skin burn classifications

Answer 2

1. Superficial (first degree)
2. Partial thickness (second degree)
3. Full thickness (third degree)

Question 3

What are photochemical skin hazards?

Answer 3

Skin pigmentation and photosensitising medication (this enhance radiation absorbance - dermal sensitivity to artificial solar radiation = cellular damage

Question 4

Compare and contrast phototoxic and photoallergic photosensitivity reactions

Answer 4

• Both photosensitising reaction
• Phototoxic: Accumulation at dermo-epidermal junction act as a chromophore = tissue damage in region
• Photoallergic:
• Occur: common with topically applied agents rather systemic medications
• Skin exposed to photo-allergen substance and contact with light radiation = cause type IV hypersensitivity contact allergic reaction
• Drug become antigen = allergic response

Question 5

How can you appropriately control this hazard in clinical setting?

Answer 5

• Administrative control: risk assessment (review procedure and safe operation)
• Regular maintenance: regular testing of machine
• apply relevant Australian Standards to minimis risk
