Workers should be cautious of Lyngbya majuscula, a naturally occurring toxic blue-green algae found in coastal waters in Queensland. Exposure to Lyngbya can lead to severe irritation in the eyes, skin, respiratory, or gastrointestinal systems. This algae, also known as mermaid's hair or fireweed, forms floating mats on the water's surface and can wash up on beaches.
Lyngbya thrives in warm temperatures, light conditions, and nutrient-rich waters. The risks involve skin and eye irritation, respiratory issues, and gastrointestinal symptoms. Those at higher risk include workers in fishing, crabbing, prawning, marine research, professional diving, and beach cleaning where algal blooms may occur.
Workers and employers should collaborate to minimize risks. Workers must follow safety instructions, use equipment properly, and seek clarification when needed. Employers or Persons Conducting a Business or Undertaking (PCBU) should manage workplace risks by employing the four-step risk management process outlined in the Work Health and Safety Act 2011. A safe working environment benefits everyone, and adherence to health and safety protocols is crucial. Use the practical advice in the How to manage work health and safety risks code of practice 2021 (PDF, 0.65 MB).
If a worker comes into contact with lyngbya, whether through inhalation, ingestion, or skin/eye exposure, take the following first aid steps:
Promptly wash the affected areas of the body with soap and water to eliminate any remaining lyngbya material. For eye contact, thoroughly flush the eyes with clean water or a saline solution. Remove clothing, such as swimwear or wet suits, to prevent lyngbya entrapment. Use a cool compress to alleviate skin irritation. Seek medical assistance if:
- The eyes are affected.
- The level and intensity of irritation raise concerns.
- The individual experiences respiratory discomfort after swimming in contaminated water or inhaling dried lyngbya material, especially if they have a pre-existing respiratory condition like asthma.
