The Crush - August 2019 - 2

Analyses of the results - sampling/chemistry data; tasting
data; vine data (variety, clone, rootstock, site); weather data
and forecasts; tank/press availability; crew/machine harvester
availability and truck availability - should be used to project
picking times. Other scheduling considerations include whether
harvest is by hand or machine, whether the grapes are optical/
machine-sorted or hand-sorted, the type of delivery vessel (lug
boxes, bins or gondolas) and transport distance from the field to
the crush pad.
Professional ag safety trainers provided advice at the July 23
Lodi Grape Harvest Safety Seminar on conducting a safe and
efficient harvest with an emphasis on work crew communication
and training. Cal Ag Safety trainer Anthony Garcia discussed
pre-harvest vineyard and equipment inspections and mechanical
harvester safety.
Pre-harvest vineyard inspections should be conducted to identify,
communicate and correct hazards associated with each vineyard
site prior to entering the field. Trash, unnecessary materials and
obstacles should be removed from vineyards prior to harvest.
Identify possible hazards such as poles, power lines and other
utilities that could be in the paths of equipment and workers.
Pre-use inspection of mechanical harvesters, tractors, gondolas
and trucks should include checks of fluid levels, hydraulic
systems (possible leaks), tire condition and air pressure. Be sure
safety guards are in place and safety warning decals are readable
or replaced if necessary. Check towing equipment, hitches and
connections for power and lights. Make sure vehicles meet
requirements for travel on public roads, including slow-moving
vehicle warning triangles mounted at the rear of vehicles at
proper heights.

The California Occupational Safety and Health Standards Board
continues to develop standards for lighting requirements for
working near ag equipment at night and issued a revised proposal
earlier this year. At the Lodi seminar, Zenith Insurance safety
consultants Erika Garrido and Diana Tejada-Guzman described
the new simpler proposed definition of night work as "activity
taking place between sunset and sunrise." They highlighted night
work concerns for harvest planning and operations:

All workers should have proper work clothing - work boots,
long-sleeved shirts, coveralls and gloves as needed. Employers
should provide personal protective equipment - high visibility
Class 2 reflective vests recommended for night work, eye
protection, ear plugs and NIOSH-approved respirator masks for
dust and smoke protection. All work crews need a first aid kit
and designated personnel trained in first aid and CPR.

 Worker fatigue: Night and early morning shifts can lead to
sleeping difficulties and fatigue. Fatigued workers are less
alert, have slower reaction times, more difficulty concentrating,
and are more prone to poor decisions with a higher potential
for injury. Evaluate and monitor workers for fatigue, especially
equipment operators.
 Limited/low visibility makes it more difficult to see and react.
This affects depth perception, color perception and contrast
sensitivity. Peripheral vision is reduced by 20 percent.
 Poor lighting reduces the ability to spot hazards and can
promote drowsiness when sleep deprived.
 Pest and wildlife activity is often nocturnal. Prepare crews for
possible encounters with snakes, rodents, insects and spiders
that could be in the vine canopy. Other wildlife such as skunks,
coyotes, deer, bobcats and bears have been sighted in vineyards.
 Criminal activity has increased in ag areas at night, including
thefts from workers' parked vehicles. Employees should not
work alone or walk alone between work sites. Break areas
and walking paths should be well lit. Train employees to be
aware of their surroundings and report unusual activity or

Employers should have written and up-to-date Cal/OSHA
required documents for their Heat Illness Prevention Program
and their workplace Injury and Illness Prevention Program.
Develop plans and instructions in advance for emergency

Garrido said, "Make vineyard entrances, exits and traffic paths
easier to see with high visibility reflective cones, flagging and
lighting. Make hands-free portable head lamps available for
workers as supplemental lighting."

Harvester and tractor equipment should only be driven by
trained and authorized operators. Workers on the ground or
near equipment should never assume the operator can see them.
All workers should know the location of the machine's kill
switch/emergency stop button. Inspect, wash, service and repair
equipment during daylight hours for the next shift.
