The phrase "acute hazard" is correct and usable in written English.
It can be used in contexts related to safety, risk assessment, or environmental concerns to describe a serious and immediate danger.
Example: "The chemical spill created an acute hazard for the workers in the area, necessitating immediate evacuation."
Alternatives: "immediate danger" or "serious risk".
We classified organophosphate toxicity using the following formal World Health Organization recommendations: class Ia (extremely hazardous), class Ib (highly hazardous), class II (moderately hazardous), class III (slightly hazardous), and class U (unlikely to present acute hazard) [ 11].
With the water gone, the lake bed could emit as much as a hundred tons of fine, caustic dust a day, leading to respiratory illness in the healthy and representing an acute hazard for people with compromised immune systems.
Outcomes evaluated soil lead concentration (employing a weighting method to assess acute hazard soil lead [areas not fully covered] and potential hazard soil lead [all soil surfaces regardless of covering status]), density of landscape coverings (6=heavy, >90% covered; 1=bare, <10% covered), lead tracked onto carpeted entryway floor mats, and entryway floor dust lead loadings.
Over 1 year, the intervention groups had significantly reduced acute hazard soil lead concentration (median change: RB, −478 ppm; NRB, −698 ppm; control, +52 ppm; Kruskal Wallis, P=0.02), enhanced landscape coverings (mean change in score: RB, +0.6; NRB, +1.5; control, −0.6; ANOVA, P<0.001), and a 50% decrease in lead tracked onto the floor mats.
Causes serious eye irritation.' and labelled with the GHS07 pictogram (acute hazard).
There has also been acute hazard to the biotic environment in the area, visibly marked by the conspicuous absence of aquatic fauna in the river.
Particular data gaps and weaknesses identified include nominal and event performance of treatment barriers for the main acute hazards, enteric viruses and protozoa, which impacts on the ability to quantify risks and appropriately manage stormwater uses.
By reducing the impacts of the chronic hazard posed by persistent volcanic degassing, resilience to acute hazards is also likely to improve.
Rural coastal communities in the Pacific, including those in the Hawai'ian islands, are at extreme risk to impacts from acute hazards such as tsunami and flash flooding, and chronic hazards such as drought and coastal erosion.
However, it can be argued that based on its diffuse but wide-ranging impacts as listed in the previous paragraph, this chronic hazard is equally as important as acute hazards.
Implementing preparedness and mitigation measures related to an invisible underlying risk factor in a time of relative low gas flux is complex and multifaceted, but is likely to contribute to increased resilience in the face of acute hazards.
