The IOSH Caribbean Branch hosted its final branch meeting for the 2018/2019 period on Friday, 26th April 2019 at the Hilton Hotel and Conference Centre in Port of Spain, Trinidad.

The branch meeting was formally called to order by the Chair, Mr. Jason Maitland as he welcomed the attendees and kicked off the evening with a safety moment on the topic of Work at Height. This is an activity that is required in numerous industries and Mr. Maitland stressed on the importance of ensuring adequate prevention and mitigation strategies to ensure that all workers go home safely.

The evening’s speaker was Mrs Chantal Lalla-Maharaj, an industrial Hygienist with over 15 years of experience at bpTT. Mrs Lalla-Maharaj indicated Industrial Hygiene covers numerous topics such as psychological health and well-being, indoor air quality and emergency response.  Practitioners in Industrial Hygiene need to anticipate, recognize, evaluate and control. Additionally, they also need to have a proper understanding of operations since sensitizing agents and carcinogenic chemicals can have short term or long term effects.

Mrs Maharaj then showed a video on why Industrial Hygiene is the right thing to do by American Industrial Hygiene Association focusing on the reason to protect ourselves and each other. Additionally, proper monitoring of Industrial Hygiene has been shown to better worker health with increased productivity. A study has shown that global gross domestic product decreased by 4% due to industrial ill health.

Mrs Maharaj spoke on the different avenues that one could take to become an Industrial Hygienist.
