This chapter introduces hazardous materials and the roles of first responders. It covers the definitions of hazardous materials and waste. Various government agencies regulate the transportation, use, and disposal of hazmat, including DOT, EPA, OSHA, and NRC. Hazmat incidents can involve thermal, radiological, asphyxiation, chemical, biological, or mechanical hazards. First responders must understand hazards and their training levels to respond safely and effectively.

Workplace hazards are the sources of potential harm or damage to someone or something in any work environment. It can be material or any activity that has the likelihood to cause injuries under specific conditions. It should be eliminated as soon as they are identified to prevent workplace incidents or fatalities.What are the 5 basic workplace hazards?

Falls and Falling Objects.
Chemical Exposure.
Fire Hazards.
Electrical Hazards.
Repetitive Motion Injury.
Typically, OSHA cites the same workplace injuries or hazards over and over. We hear that falls are dangerous, to be cautious when handling chemicals, or to be aware of fire hazards. But, when it comes down to it, do companies have a strategy in place to ensure they are protecting their workers and ensuring their liability is defended?
What are the 5 major hazards in the workplace?
Falls and Falling Objects
Chemical Exposure
Fire Hazards
Electrical Hazards
Repetitive Motion Injury
Where OSHA cites the most accidents is in the construction industry, which is not really a surprise due to the dangerous work performed on job sites. However, no matter the industry there are workplace hazards – including sitting at a desk in a cozy office job.
At the heart of avoiding accidents or identifying hazards is ensuring your workplace or job site has individuals performing tasks who are properly trained. Training is the key to prevention! You’ll see this trend in our “Prevention Tip(s)!” below.
Workplace Hazard #1: Falls and Falling Objects
Approximately 19,565 people die in the U.S. annually due to injuries caused by unintentional falls
Slips, trip and fall injuries cost employers approximately $40,000 per incident;
About 9.2 million people were treated in emergency rooms for fall-related injuries in 2016.
65% of fall-related injuries occur as a result of falls from same-level walking surfaces;
In 2017, there were 366 fatal falls to a lower level out of 971 construction fatalities
CFR 1926.501 Fall Protection is the single most cited workplace violation by the OSHA
85% of worker’s compensation claims are attributed to employees slipping on slick floors (Industrial Safety & Occupational Health Markets 5th edition)
Prevention Tip!
Since 2012, OSHA has recognized training as the best way to minimize fall injuries: Use myComply to book training and keep track of who has been trained!
Workplace Hazard #2: Chemical Exposure
Breathing of contaminated air is the most common way that workplace chemicals enter the body.
Centers for Disease Control and Prevention estimate more than 32 million workers in the United States are potentially exposed to chemicals that can be absorbed through the skin.
Roughly 860,000 illnesses resulting from chemical exposure occur in the workplace every year.
Employers must develop, im
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

Title: Sense of Smell
Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path
