Hazards and Risks

What is a Hazard?

A hazard in is any source or situation with the potential to cause harm, injury, or adverse health effects to employees or damage to property.

What is a Risk?

A risk refers to any potential threat to the health, safety, or well-being of employees, as well as to the organization's assets,

You first need to identify hazards to assess the associated risks.

Identifying all potential risks is essential to making informed decisions and minimizing hazards while performing tasks.

Hazards can be categorized into two types:

1. Acute hazards - hazards that present immediate signs of danger, such as a glass bottle breaking on the floor, which increases the risk of injury from stepping on glass shards.

2. Chronic hazards - no immediate effects, like long-term exposure to harmful chemicals, which may lead to health issues

All hazards fall into one of six categories:

1. Physical - obstacles in walkways, lighting fixtures, unsafe machinery.

2. Chemical - leaks of liquids or gases within the workplace, which can affect the respiratory tract or cause poisoning.

3. Ergonomic - poor workspace design, such as cramped cubicles in offices, leading to low morale and productivity.

4. Radiation - safety procedures like using lead jackets for protection from x-rays.

5. Psychological - poor management styles, like micromanagement, leading to increased stress and decreased productivity.

6. Biological - in food, maintaining cleanliness to minimize pathogens and enhance safety.

Risk Assessment Matrix

A Risk Assessment Matrix is a tool used to evaluate and prioritize risks based on their likelihood and potential impact. It typically consists of a grid where the likelihood and consequence of each risk are assessed and assigned a score, often using a numerical scale. These scores help in categorizing risks into different levels of severity, from low to high, and guide decision-making regarding risk management and mitigation strategies.

Two types of Risk Assessment Matrix:

1. Qualitative Risk Assessment Matrix:

This matrix typically categorizes risks based on subjective assessments of their impact and probability. It assigns ratings such as low, medium, and high to both severity and likelihood.

2. Quantitative Risk Assessment Matrix:

This matrix quantifies risks using numerical values, often incorporating statistical analysis to assess the probability and potential impact of each risk. It may involve techniques like Monte Carlo simulation or decision trees to assign values to risks.

Chemical Hazards

A hazardous substance refers to any material or chemical products used or generated in a workplace setting, capable of causing harm upon contact with the human body eg. dust, gasses, fumes, biological agents, natural substances,

Workers can be exposed to hazardous substances through:

(1) Ingestion – consumption of substances by mouth.

(2) Injection – substance enters through a break in the skin.

(3) Inhalation – substance enters the body during breathing.

(4) Absorption – substance passes through skin.

Procuring chemicals, hazardous or not, is a serious process. Once chemicals are needed, it's crucial to follow specific guidelines for their use and storage.

Here are some important considerations:

Storage and Identification - Chemicals should be stored in a designated area solely for that purpose.

The storage area must be clearly marked and distinctly identified.

It should be constructed to contain leakages and spillages within the immediate area.

Mitigative measures, such as absorbent materials and clean water, should be readily available for cleanup.

Security and Access:

Storage areas must be locked or secured to prevent unauthorized access.

Adequate ventilation in the vicinity of stored chemicals is essential to manage vapors and gases emitted by certain materials.

Handling and Training:

Personnel handling chemicals must have access to proper training and certification.

Personal protective equipment (PPE) eg. Gloves, Respirators, Coveralls, Face shields should be stored separately but be easily accessible.

Training should cover the use of material safety data sheets (MSDS) and basic emergency response procedures.

Container and Storage Guidelines:

Chemicals should not be stored in containers that are unsuitable or misleading.

They should be stored according to classification and physical state (e.g., viscous chemicals stored below solids).

Food for human or animal consumption should never be stored with chemicals.

Exposure and Safety:

Exposure to hazardous chemicals can occur through respiratory, oral, dermal, injective, or ocular contact.

The Control of Substances Hazardous to Health (CoSSH) emphasizes safety measures to prevent health risks associa

ted with chemical exposure.

Working Safely

Maintaining health and safety on a farm involves careful consideration of both human and animal well-being, particularly when handling livestock, which can be easily startled. Creating a calm and secure environment is essential for both the handler and the animals.

Farm Safety & Children

Supervision: Keep a close watch on children, especially around agricultural equipment, water sources, and animals.

Machinery Safety: Children should be supervised near farm machinery at all times, even when not in use. Educate them about the dangers and establish clear boundaries for where they can and cannot go on the farm.

Water Safety: Prevent drowning risks by ensuring children are never left unsupervised near ponds, canals, or water troughs. Erect secure fencing and cover water troughs to avoid accidental slips.

Animal Interaction: Teach children safe ways to engage with animals, emphasizing quiet approaches and proper protective gear, such as helmets near horses.

Fall Prevention: Maintain barriers and gates to keep children at a safe distance from animals.

Slips, Trips & Falls

Slips, trips, and falls (STFs) are types of accidents that involve a person losing their balance or footing, resulting in a fall.

Slips: Slips occur when there is insufficient friction between the footwear and the walking surface. This can happen due to wet or oily surfaces, loose debris, or polished floors. Slips often occur suddenly and can lead to falls if the person cannot regain their balance.

Trips: Trips happen when a person's foot collides with an object, causing them to lose their balance. Common trip hazards include uneven flooring, thresholds, cables or cords across walkways, and cluttered surfaces. Trips can lead to falls if the person cannot recover their balance or if they stumble into another obstacle.

Falls: Falls occur when a person ends up on the ground or at a lower level unintentionally. Falls can result from slipping or tripping, losing balance on unstable surfaces, or falling from heights such as ladders or platforms. Falls can cause injuries ranging from minor bruises to severe fractures or head injuries, depending on the height and surface involved.

Slips, trips and falls are leading causes of farm-related injuries, contributing significantly to work-related fatalities and impairments.

However they can be prevented by:

Understanding and using one's center of gravity, such as lifting with legs rather than back, improves safety and efficiency.

Be mindful of uneven surfaces, debris, and obstacles that can cause trips or slips, especially under muddy or wet conditions.

Differentiate between non-slip, moderately slippery, and slippery surfaces. Use appropriate flooring materials like rubber mats or rough-textured concrete to enhance traction.

Fall Management: In case of a fall, knowing how to relax and roll with the impact can minimize injuries. Prompt first aid is crucial for managing any sustained injuries effectively.

Biological Hazards.

A biological hazard refers to any biological substance or condition that poses a threat to the health of living organisms, primarily humans. These hazards can arise from various sources, including microorganisms (such as bacteria, viruses, fungi, and parasites), toxins produced by these microorganisms, allergens from plants or animals, and biological materials such as blood or bodily fluids.

What is Zoonosis?

Zoonosis refers to diseases that can be transmitted from animals to humans, either directly or indirectly. These diseases are caused by pathogens such as viruses, bacteria, parasites, fungi, and prions that can spread between animals and humans through various routes, including direct contact, consumption of contaminated food or water, inhalation of airborne particles, or through vectors like mosquitoes or ticks.

History and Significance.

Zoonotic diseases have been known throughout history and continue to pose significant public health challenges globally.

Some notable historical examples include:

Plague: The Black Death, caused by the bacterium Yersinia pestis and transmitted by fleas from rats to humans, killed millions in Europe during the 14th century.

Influenza: Various strains of influenza viruses, including the H1N1 "Spanish flu" and more recent avian and swine flu outbreaks, have crossed from animals to humans.

Symptoms

The symptoms of zoonotic diseases can vary widely depending on the specific pathogen involved. Common symptoms may include fever, fatigue, respiratory issues, gastrointestinal symptoms (such as diarrhea or vomiting), skin lesions, and in severe cases, organ failure or death.

Pigs and Zoonosis.

Pigs are significant in the context of zoonotic diseases due to their role as hosts for various pathogens that can infect humans.

Some zoonotic diseases associated with pigs include:

Swine Influenza: Pigs can be infected with influenza viruses that have the potential to transmit to humans, causing respiratory illness.

Salmonellosis: Bacteria of the Salmonella genus can be transmitted from pigs to humans through contaminated pork products or direct contact, causing gastrointestinal illness.

Hepatitis E: This viral infection can be transmitted through consumption of undercooked pork or direct contact with infected pigs, leading to hepatitis symptoms in humans.

Prevention and Control

Preventing zoonotic diseases involves several key strategies:

Hygiene Practices: Practicing good hygiene, such as frequent handwashing with soap and water after handling animals, especially pigs, and avoiding touching the face or mouth before washing hands, can reduce the risk of infection.

Food Safety: Cooking meat, including pork, thoroughly to kill pathogens, and avoiding consumption of raw or undercooked meat products can prevent foodborne zoonoses.

Vector Control: Preventing exposure to disease-carrying vectors like mosquitoes or ticks through insect repellents, protective clothing, and environmental control measures.

Vaccination: Vaccinating animals against specific zoonotic pathogens can reduce the prevalence of disease in animal populations and lower the risk of transmission to humans.

Surveillance and Early Detection: Monitoring animal populations and conducting regular surveillance for zoonotic diseases can help identify outbreaks early and implement control measures promptly.

Public Education: Educating the public, particularly those at higher risk of exposure (such as farmers, veterinarians, and healthcare workers), about the risks of zoonotic diseases and how to prevent them is essential for reducing transmission.

Zoonoses represent a significant public health concern globally due to their potential to cause outbreaks and epidemics. Understanding the routes of transmission, symptoms, and preventive measures, particularly regarding pigs and other livestock, is crucial for mitigating the risk of zoonotic diseases and ensuring the health and safety of both human

and animal populations.

An electrical circuit is a closed loop through which electric current can flow. It consists of components such as wires, switches, resistors, capacitors, and power sources (like batteries or generators). Electric circuits allow electricity to power devices and perform functions by controlling the flow of electrons through the circuit components.

Conductors and Insulators

Understanding the properties of conductors and insulators is important in designing safe and efficient electrical systems.

Conductors: Are materials that allow electricity to pass through them easily because they have loosely bound electrons that can move freely. Metals like copper, aluminum, and silver are excellent conductors.

Insulators: Are materials that do not allow electricity to flow through them easily because their electrons are tightly bound. Examples include rubber, plastic, glass, and ceramic. Insulators are used to protect against electric shocks and to prevent electricity from leaking out of wires and cables.

Static Electricity.

Static electricity is the accumulation of electric charges on the surface of objects through friction or separation. It causes effects like mild shocks, attraction of small objects, and can be discharged as sparks. Examples include rubbing a balloon on hair to create static attraction or walking across a carpet and receiving a static shock when touching a metal doorknob. In industrial settings, static electricity can pose risks in environments with flammable gasses or vapors, potentially causing ignition and fires. Understanding static electricity helps in managing its effects and utilizing it safely.
