Transcript Aquaculture Safety

1
Objectives
1. To identify common hazards located in an
aquaculture laboratory.
2. To examine methods of preventing and treating
different hazards.
3. To understand the importance of safety in the
laboratory.
4. To describe hazards found in the aquacultural
workplace.
2
The Laboratory
• Is where observations, research and
experimentation occur
• Possesses the following types of hazards:
– physical
– chemical
3
Physical Hazards
• Account for the dangers created by the operator
or the condition and use of an object
• In the aquatic laboratory may be divided into the
following:
– electrical
– mechanical
– water
– human error
4
Electrical Hazards
• Are common in aquaculture settings
due to the high amount of moisture
and electrical equipment present
• Often cause electrical shocks when a
person comes into contact with faulty
wires or improperly grounded
equipment
• May cause sparks or fire
Grounded – an electrical circuit which at one point is
connected to the earth, and acts as a reservoir of charge
5
Electrical Hazards
• Include the following:
– exposed wires
– water on or near electrical
outlets or equipment
– not using proper size or length of
wire or battery
– not having outlets or other
energy sources grounded
6
Preventing Electrical
Hazards
• On or near the water include, but are not
limited to, the following:
– using the proper size and type of wire
– using the correct size of power supply
– having all power supplies properly grounded
– keeping all areas surrounding electrical
supplies dry
– having the ability to turn off
circuits at a power source
7
Mechanical Hazards
• Occur due to the following:
– improper use of machinery
– poor upkeep of machinery
– faulty equipment
– operator not paying attention
to task
8
Preventing Mechanical
Hazards
• In the aquaculture laboratory include, but are not
limited to, the following:
– paying attention to the task at hand
– properly storing equipment
– understanding how to properly use and maintain
equipment
– replacing old or damaged equipment
9
Water Hazards
• Occur frequently in aquaculture labs due to the
presence of and experimentation involving water
• Occur when water is spilt on floors and cabinets,
allowing people to slip and fall or water to come
into contact with electrical appliances
• Include improper management of water, which
may spread diseases or attract insects
10
Preventing Water Hazards
• Can be accomplished by:
– cleaning up water immediately
after it is spilt
– maintaining water to keep it
clean and fresh
– keep water away from electrical
outlets and appliances
11
Human Error
• May also be classified as either
electrical, mechanical or water
related
• Occurs when the danger is caused
by the person rather than the
equipment
• Is the most frequent cause of
injuries in the laboratory
12
Human Error
• Is caused by the following:
– not paying attention
– not following directions
– not understanding the task
– not knowing how to properly
operate equipment
– not wearing proper personal
protective equipment (PPE)
13
Preventing Human Error
Hazards
• Can be accomplished through the following:
– obey all laboratory rules set up by the instructor
– read and follow all instructions given by the
instructor
– become familiar with equipment before using it
– keep a clean and organized work area
– wear all designated
personal protective
equipment
14
Personal Protective
Equipment
• In the aquaculture laboratory usually includes
the following:
– gloves
– goggles
– closed toe shoes
– long pants
– no loose fitting clothing
15
Chemical Hazards
• Occur through the use of chemicals to
maintain the aquaculture environment,
such as improving water pH
• Are classified as any agent which is:
– ignitable: flash point below 140 degrees
Fahrenheit
– corrosive: pH levels are less than 2.0 or
above 12.5
– reactive: explodes or releases harmful fuels in
response to contact with another agent
– toxic: poisonous
Flash Point – the lowest temperature at which the
vapor of a flammable object will ignite
16
Material Safety Data Sheets
(MSDS)
• Contain information regarding the hazards and
cautions of a chemical
• Provide workers and emergency personnel
with procedures concerning safe handling
• Include the physical properties of a substance
as well as procedures for first aid, safe
disposal, storage and health effects
• Should always be consulted before using a
chemical
17
Labels
• Are required by law to be placed on
chemicals
• Contain information from the MSDS in a
quick, easily accessible format
• Are usually found in the following form:
Fire Hazard
0 (will not burn) – 4 (very easily flammable)
Health Hazard
0 (ordinary) – 4 (deadly)
Reactivity Hazard
0 (stable) – 4 (may detonate)
Specific Hazard/Personal Protection
18
Responding to Safety
Hazards
• Should be completed as quickly as possible in a
laboratory to prevent harm
• Includes knowing how to perform the following:
– basic first aid
– location of exits
– location of safety equipment
– how to use safety equipment
19
Basic First Aid
• Involves knowing how to do the following:
– apply bandages and pressure to cuts in order
to prevent bleeding
– flush burns immediately with cold water
– flush eyes with water immediately after
contact with chemical
– report all injuries to your instructor
immediately
20
Safety Equipment
• Is located throughout the laboratory
• Requires knowing the locations of each item
• Includes the following:
– fire extinguisher/fire blanket
– eye wash
– first aid kit
– emergency shut off buttons
21
Workplace Hazards
• Are important to recognize since many
operations use chemicals and equipment
in wet locations
• Are similar to those found in the
laboratory, though often found on a larger
scale
• Not found in the laboratory
include the following:
– noise
– sleep deprivation
– nighttime work
22
Noise
• Is produced by power tools and long term
exposure may cause permanent hearing loss
• Limits the ability to hear alarms or sirens
• Includes wearing earmuffs or earplugs for
protection
23
Sleep Deprivation
• Occurs because many aquaculturists,
especially those working at sea, work around
the clock in alternating shifts
• Causes falls, knife cuts and various other
injuries due to human error
• Allows for slower reaction time and impairs
decision making
24
Nighttime Work
• Increases the chances of fatigue among workers
• Limits the amount of light and visual perception
• Hinders the awareness of surroundings as well
as co-worker presence
25
Occupational Safety & Health
Administration (OSHA)
• Provides enforcement of work safety and health
standards throughout the United States
• Defines associated hazards and protective
measures for different areas of work
• Classifies aquaculture standards under the
agriculture category
26
Occupational Safety & Health
Administration (OSHA)
• Standards concerning aquaculture include
the following:
– establishing guidelines for safe operation of
equipment
– placing limits on how much time may be spent
working continuously by an employee
– requires certain environmental factors must be
met in the workplace
– listing suggested PPE
