Malaysia at risk of deadly humidity threat
PETALING JAYA: It's not merely the heat – it's the humidity that poses a lethal threat. Experts warn of a wet-bulb temperature (WBT) threat as Malaysia sweats through a silent, rising danger. And with the heat expected to rise in the coming months, Malaysians should be prepared to deal with this lesser-known but deadly phenomenon. A patient's core body temperature will normally rise to dangerous or even fatal levels in a matter of hours, according to the experts. Prof Dr Sharifa Ezat Wan Puteh of Universiti Kebangsaan Malaysia (UKM) said studies have shown that WBT can occur even when the temperature is as low as 31°C. 'The US National Weather Service considers WBT temperatures of 31°C or higher to be in 'extreme danger'. This is considered relatively low, and it supports the idea that the human body's ability to cope with heat stress is compromised even at lower thresholds than once believed,' she said when contacted yesterday. Sharifa said that certain groups are more susceptible to the dangers of WBT, such as the elderly, pregnant women, children, outdoor workers and individuals with underlying health comorbidities. 'Staying in shaded areas, hydrating frequently, limiting physical exertion and outdoor exposure, and wearing light, breathable clothing may reduce the risk of hyperthermia (internal body temperature rising),' she added. Sharifa suggested that the respective agencies work together to alert the public to the dangers of extreme heat exposure and WBT. 'The Department of Occupational Safety and Health (DOSH) should also advise officers to keep workers out of open areas that are exposed to heat, wind or humidity,' she added. CLICK TO ENLARGE Sustained temperatures between 31°C and about 35°C, along with humidity levels above 90%, are known to cause WBT in a specific area. It is considered extreme hyperthermia and often fatal if the core body temperature reaches 42°C and above. On June 2, the Meteorological Department (MetMalaysia) issued a Level 1 advisory after six areas in Peninsular Malaysia experienced maximum daily temperatures of between 35°C and 37°C for three consecutive days. Universiti Malaya (UM) public health medicine specialist Prof Dr Victor Hoe voiced concern over the prolonged heat and humidity the nation is currently facing, which is expected to last through the coming months. 'What we're facing is more than just uncomfortable weather. 'This is a growing public health and safety concern that requires attention, empathy and coordinated action,' he said when contacted. Hoe said that a person's body will naturally regulate internal temperature by producing sweat, which cools the body when it evaporates. 'But when the air is very humid, sweat doesn't evaporate efficiently. This reduces our body's ability to cool down, leading to overheating, which can be dangerous or even deadly,' he said. Signs to watch for heat exhaustion or heatstroke include tiredness, dizziness, nausea, confusion, rapid pulses and unconsciousness. Hoe urged the public to remain adequately hydrated by drinking water consistently throughout the day. 'Avoid outdoor activity during the hottest part of the day, such as between 12pm and 3pm. 'Wear loose, light-coloured clothing and stay in shaded or air-conditioned areas. 'Check in with elderly neighbours or family members, especially those living alone,' he said. UM's vice-chancellor (research & innovation) Prof Dr Sanjay Rampal described WBT as a public health threat which may happen even if temperatures are lower than 35°C. 'Currently, MetMalaysia's three-tier alert system focuses only on dry-bulb temperature but does not account for the role of humidity. We may consider a heat index that combines temperature and humidity measurements,' he suggested. Dr Sanjay added that MetMalaysia should work in collaboration with relevant agencies by providing them with meteorological data, which could then be translated into specific health advisories for the general public. In response to the rising temperatures, Dr Sanjay cautioned parents against leaving their children or elderly relatives unattended in parked vehicles.

Strict vetting can save lives
PETALING JAYA: Thorough background checks should be carried out on those seeking jobs as commercial vehicle drivers, say road safety experts. Malaysian Road and Transportation Safety Association president Md Hairolazaman Muhamed Nor called for enhanced screening and monitoring measures to be taken. 'Ongoing monitoring, including drug and alcohol testing as well as performance evaluations, is important,' he said. However, he said it could be discriminatory to impose a blanket ban on former convicts looking for employment in the sector. 'It may unfairly exclude responsible and reformed individuals from job opportunities. 'Instead, policies that disqualify persons with recent serious or violent offences can be implemented. 'Comprehensive assessments rather than blanket bans should be used to evaluate each driver's suitability,' he added. Md Hairolazaman proposed the mandatory use of dashcams and CCTVs inside heavy vehicles. 'Continuous recording of driver behaviour and vehicle conditions can also assist investigations and promote accountability,' he said, adding that it should be done alongside regulatory measures, driver training, infrastructure improvements and enforcement. He also proposed increased adoption of ISO 39001 due to the recent spate of road crashes involving heavy vehicles. ISO 39001 is an international standard for road traffic safety management systems, providing a framework for organisations to reduce and prevent road fatalities and injuries. Universiti Kebangsaan Malaysia's Dr Nurrul Hafeezah Sahak called for a zero-tolerance approach, such as immediate suspension, for drivers found taking banned substances. 'Screenings should be conducted at the pre-employment phase and also at periodic intervals,' said the Faculty of Science and Technology lecturer. She said public involvement is equally crucial in enhancing road safety, adding that unsafe lorry driving should be reported immediately. 'Transport companies must ensure timely and appropriate investigations of complaints addressed against them as well,' she said. Universiti Putra Malaysia's Prof Dr Kulanthayan KC Mani said road crashes are preventable and that the probability of technical issues in heavy goods vehicles can be reduced if they are well maintained. 'These vehicles are highly used, so maintenance requirements must be met. 'When heavy vehicles carry loads, the total weight also increases, which can make it harder to control. 'Driving fast makes the situation even more challenging,' said Kulanthayan, who heads the Putra Injury Prevention and Safety Promotion Group. He said it is important to monitor drivers, adding that companies should take responsibility too. 'The installation of systems like dashcams can possibly reveal how an incident happened, enhancing crash investigations. 'With more vehicles having dashcams, it can also enhance driving etiquette, as the chances of being seen committing violations will be high,' he said, adding that the idea also applied to private vehicles. A lorry carrying gravel rammed a truck carrying nine Federal Reserve Unit personnel on Tuesday, resulting in their deaths. Preliminary investigations revealed that the lorry had a malfunction causing its steering system to fail. Perak police chief Datuk Comm Noor Hisam Nordin said the lorry driver had six prior criminal cases mostly related to narcotics and had multiple outstanding traffic summonses.
