“…When studied in temperate (258 C) and warm conditions (308 C) at that external work rate (30 W), this expectation was realized (N = 12; Ref. 13). However, in the heat (358 C, water vapor pressure 2.3 kPa, 40% RH), significant thermal loading was observed with the thresholds for moderate (.38.58 C) and profound hyperthermia (.40.08 C) predicted to occur within 105 and 180 minutes, respectively.…”

There is often a fine line between providing appropriate personal protection and compromising capability. In some situations, protection must come first. In other circumstances, capability becomes paramount. In the military, mission-specific objectives can force personal protection to be less than ideal. Indeed, levels of protection appropriate within the civilian context could jeopardise health and operational success, and for operations conducted in the heat involving load carriage and armored protection with almost total-body clothing coverage, it is the likely thermal impediment to performance that perhaps first comes to mind. Although this consideration is appropriate, it may direct attention away from the actual cause of, and therefore preventative solutions to, physiological collapse. For instance, although classical heat illness absolutely occurs at the age extremes, and it may affect all people when air temperatures are exceptionally hot, frank hyperthermia is not generally the primary cause of exhaustion when healthy clothed individuals are working in the heat. Instead, another homoeostatic process is implicated; blood pressure regulation. In addition to participating in temperature regulation, the cardiovascular system supports oxygen delivery, blood pressure regulatory, and waste removal requirements. Therefore, the elevated cardiac output accompanying work must be shared. Accordingly, the case will be developed that thermoregulatory failure is often not the primary causal mechanism for soldier collapse, although such individuals may be hyperthermic. Alternatively, moderately, but not excessively, hyperthermic soldiers working under these conditions are perhaps more likely to collapse from cardiovascular insufficiency that precipitates uncompensable hypotension.

“…Also, the examination towards physiological strain at the temperature 35°C needs to be done. 55 Hence to design and develop clothing that could give more thermal regulation during hot climatic conditions and comfort to the wearer is very much required. The tests should be done to analyze the thermal balance of the bike rider’s protective clothing.…”

Motorcycle protective clothing is designed to protect motorcyclists from injuries during accidents. It helps to protect the motorcyclist and pillion passengers during the collision and acts as a barrier between the rider’s skin and tarmac surface. Soft tissue trauma is common in motorcycle accidents and protective clothing can protect the soft tissue of the riders up to a certain extent during accidents. Though there are many reasons for road accidents and injuries, the reasons such as uncomfortable clothing, thermally inefficient protective clothing during hot climatic conditions, and ineffective performance of the personal protective equipment (PPE) are also to be considered seriously. Motorcycle clothing is specially designed in such a way that it could give better protection against impact and abrasion during the collision. An increase in the usage of the motorcycle has also in turn increased the crash statistics. This paper deals with the significance of motorcycle clothing, materials, test standards, and their performance characteristics. As per the review results, most of the motorcycle protective clothing has failed to meet out the quality standard protocols. Impact resistance, abrasion resistance, thermal comfort, and ergonomics are the major areas where more focus is required. Design of appropriate fabrics assuring requisites of motorcycle clothing is very challenging and extensive research is still intended in these areas.

“…More than a quarter of garments fail under crash conditions . Many garments impose significant thermal strain in summer conditions and may compromise safety through impaired functioning and fatigue (de Rome et al, 2015;de Rome, 2019). Moreover, thermal discomfort leads many riders to choose to ride unprotected.…”

Proceedings of the 2023 annual Australasian Road Safety Conference held in Cairns, Queensland, Australia. The proceedings provide the Extended Abstracts, Posters, Infographics describing research, educational and policing program implementation and policy and management strategies related to all aspects of road safety and especially related to the conference theme of Safe Travel for All. Almost 600 delegates from 22 countries attended the hybrid conference. Authors of accepted Extended Abstracts represented international and local institutions from all aspects of their respective communities including research centres, private companies, government agencies and community groups. These Extended Abstracts provide an indication of the important work being done in Australia, New Zealand and internationally as part of the United Nations, One UN Vision for Road Safety to reduce the number of crashes on the road by 50 percent by 2030. Over 200 Extended Abstract manuscripts were accepted for face-to-face (F2F), virtual and poster sessions. Each Extended Abstract was peer-reviewed by two experts with relevant expertise. Authors were also provided the option of submitting a Full Paper. Those authors who chose to submit a Full Paper for consideration in the Journal of Road Safety (JRS) could do so based on the outcome of the peer review of their Extended Abstract. Submitted Full Papers undergo peer-review by three independent experts matched by their sector. The matching pairs academic authors with academic reviewers and practitioner authors with practitioner reviewers. Inclusion in the JRS follows acceptance by the peer-reviewers. The conference covered a comprehensive range of topics including speed, infrastructure and road design, cyclist safety, motorcyclist safety, pedestrian safety, road safety education, licensing, vehicle design, impairment due to distraction from mobile phones, alcohol, drugs as well as the impacts of climate change on future transport systems road safety, road safety issues for Indigenous people groups across New Zealand and Australia, integrating road safety into local Government, automated enforcement, gig economy road safety, older drivers, etc.
